Why Greece

One country for the conference and the islands for the reward

Athens has direct flights from every major European hub, a 6,000-delegate congress centre and hotels of 500 rooms and more within a short transfer of each other. That makes it the easiest Greek sell for a large or mixed-agenda group: the conference, the opening and the gala in one city, with the Acropolis as the backdrop.

The islands are the reward. Mykonos and Santorini for groups of 50 to 150 where the event itself is the trophy; Crete for multi-day incentive programmes that never repeat an experience; the Peloponnese, Corfu and Rhodes for clients who have done the classics and want something theirs.

For a DMC in Greece, the point is the match: Athens for 400 to 2,000 delegates, an island for 50 to 150, Crete or Costa Navarino for 300 who need a resort with its own conference centre. One team, one contract, and the destination chosen for the group size and the month, not the other way round. When the dates fall outside the island season, the same team runs ONE Event Cyprus, with flights all year.

In 2026 Condé Nast Traveller readers voted Greece the best country in the world, and ONE Event Greece won the World MICE Award for Greece and Cyprus.

What we deliver

One team from the first site inspection to the last transfer

Incentive travel, international conferences, corporate meetings, product launches, team building, gala dinners and brand activations: the full MICE range in Greece, delivered by one team from Athens. Our most common group is 100 to 250 people; we have delivered programmes for 1,500. We work with incentive agencies and PCOs, and directly with companies organising their own event in Greece.

l

Programme design and budgeting

Led by a managing partner with an accountant’s training: a programme that fits the brief and the number, from day one.

Venue and destination selection

Seven destinations and the venues to match the group size, so the location fits the group rather than the group the location.

Hotel and room-block management

We hold and manage the room blocks, from Athens’ 500-room hotels to resort conference centres such as Costa Navarino and Creta Maris and the island boutique collections.

On-site management

Our own project managers on the ground for the whole programme, in Greek and English.

Production and suppliers

AV, catering, transport, entertainment and branding through partners we have worked with for years, on the mainland and the islands.

Island logistics

Group transfers booked ahead, seasonal flight planning, ferry or charter options: what decides whether a Greek programme runs smoothly.

Seven destinations

Where the programme goes depends on what it has to achieve

Athens

Conferences, launches and corporate events at scale: direct flights, full congress infrastructure, the city as backdrop.

Crete

Multi-day incentive programmes: the largest island, with mountains, gorges, coast and gastronomy enough for a week without repeating a day.

Mykonos

High-end incentives and VIP entertainment for 50 to 150, where the goal is to reward rather than to teach.

Santorini

Gala dinners and awards nights on the Caldera, when the setting is the trophy.

Corfu

Villa-based leadership offsites and small high-touch groups; refined rather than loud.

Peloponnese

Story-driven incentives for clients who have done the islands: Costa Navarino, olive groves, villages, Pylos.

Rhodes

Large incentive groups that want culture with the beach: a 400-room resort beside a medieval old town.

Each destination links to its detailed page on one-event.gr. Cyprus has its own page: ONE Event Cyprus.

Athens is the hub: direct international flights all year, and a 45-minute domestic flight to Mykonos, Santorini and Crete. The islands have direct international flights from April to October only; outside that window the group connects through Athens, which we build into the programme. For a winter programme without the connection, see ONE Event Cyprus.

Best months. April to June and September to November on the mainland and the islands: warm, fewer crowds than July and August, and better availability of hotels, venues and island transfers. July and August are peak season; we can work then, but island taxis and venues need booking well ahead.

Experiences

Incentive travel in Greece: what a group cannot book on its own

Athens

A village evening with the Acropolis in view

A Greek village evening with the Acropolis in view, or a fishing port privatised for the night: the closing night that keeps a large group together.

Peloponnese

A day as a farmer, dinner under the olive trees

A day as a farmer or bee-keeper, dinner under centuries-old olive trees, and set-ups at the Odyssey film locations near Pylos.

Santorini

Sunset cruise to the volcano, dinner on the Caldera

A sunset cruise to the volcano, a private winery and dinner on the Caldera: the gala that is the photo.

Mykonos

Schooner, sunset and our own treasure hunt

A beach-hopping schooner, sunset from the island’s highest point and our own treasure hunt: the Mykonos most visitors never see.

Crete

A 4×4 day through rural Crete

A self-drive 4×4 day through rural Crete, ending with a feast in a village that is yours for the evening.

Rhodes

A gala in the medieval old town

A gala for the full group in the medieval old town of Rhodes, with a 400-room resort as the base.

For sustainability requirements: village and farm programmes that put the group’s spend with local producers, certified hotels where the client asks for them, and paper-free registration and agendas.

A technology company’s meeting for 400 in Athens in 2025: sessions at a city hotel, an evening with the Acropolis in view and a closing dinner at a venue privatised for the group.

What sets the limit is not our resources, it’s the destination: the room blocks, the largest function space, the transport available on your dates. That’s why we choose the right location for the group size from day one, rather than forcing a location to fit.Alexis Onoufriou, Managing Partner, ONE Event Greece

Questions we are asked about Greece

Before you brief us

Is Greece good for corporate incentive travel?
Yes. Direct flights from most major European cities, warm weather from April to October, and city, island and countryside settings within one country and one time zone. Athens for scale, the islands for the reward, the Peloponnese for groups that want something less known.
What is the best time of year for a corporate event in Greece?
April to June and September to November: warm, fewer crowds than July and August, and better availability of hotels, venues and transfers. July and August are peak season and island transport gets tight without early booking.
Athens or the islands for a corporate group?
Athens for conferences, launches and any group above 200: direct flights all year, a 6,000-delegate congress centre and 500-room hotels. The islands for incentives of 50 to 150 between April and October, when the reward is the point. Many programmes do both: two days of sessions in Athens, two days on an island.
How large a group can Mykonos or Santorini take?
Exclusive-use venues on the islands work best for 50 to 150 people. Groups of 200 and more are better placed in Athens, Crete, the Peloponnese or Cyprus, which have the hotel inventory and the large venues.
Are airport transfers on the islands reliable for groups?
Yes, if pre-booked. Mykonos and Santorini have a limited number of licensed taxis; we arrange private group transfers in advance, especially from June to September when taxi queues can run to an hour.
Which conference venues in Athens take more than 1,000 delegates?
The Megaron Athens International Conference Centre: 18 spaces, a 1,960-seat main hall and up to 6,000 delegates across the building, with the InterContinental, Grand Hyatt and Conrad within a short transfer. Outside Athens, Costa Navarino (1,200 theatre) and Creta Maris (1,700 theatre) take large plenaries.
What does a DMC in Greece do that an agency abroad cannot?
It holds the local relationships: the village that opens its square for one night, the winery that closes for the group, the island transfers booked before the season sells out, and project managers on site for the whole programme. We are based in Athens and work in Greek and English.
Can you organise our company event in Greece if we don’t have an agency?
Yes. Most of our corporate clients come to us directly: HR, marketing or an executive assistant with a date, a group size and a goal. We take it from there: hotels, venues, programme, flights between Athens and the islands and the team on site, and you deal with one person throughout.
