Can I leave my luggage in the cabin while I go ashore?

If you are on a day trip to France or minicruise to Spain and you have been allocated the same cabin number both ways you may leave non valuable items in the cabin. Please remember to take your passport and ticket with you.

For security reasons it is not possible for passengers to leave their luggage in the baggage room.
