Help! We are travelling from Portsmouth to St Malo on Brittany Ferries Bretagne. We are booked into a 4 berth club cabin not realising how small it is. My 2 year old is currently in a cot (very restless sleeper) I was planning for him to sleep in his blow up bed with raised sides on the ferry but don't think there will be enough room for it. He will not sleep with either of us in the bed so my query is should I put him in the lowest bunk and hope for the best? I am already expecting a night of no sleep!! Any tips extremely welcome.
