MICE strengths

  • 177 rooms and suites, enough for a residential group of 100 or more
  • Five seminar rooms for breakouts of 10 to 60 people (directories)
  • Thalassotherapy centre linked to the hotel for wellness incentives
  • Seafront location on the Sillon, close to the walled city
  • Saint-Malo congress centre, the Palais du Grand Large, within the same town

Why choose it

The natural base for a seaside residential seminar in Saint-Malo, combining breakout rooms, sea air and wellness, or for lodging delegates of an event at the Palais du Grand Large.

Possible limits

Meeting rooms are sized for breakouts, not plenaries: a larger plenary would be held at the Palais du Grand Large. Seminar details are from directories and should be confirmed.

Airport

Dinard-Bretagne airport is the nearest, across the Rance estuary; Rennes airport is the main alternative.

Station

Saint-Malo station, a short taxi ride; allow roughly 2h30 by TGV from Paris-Montparnasse.
