I'm looking at taking the ferry to St Malo this summer - would be me, DH, and three DCs of 9, 6, and 6 months. I've never been on a ferry like this before - what's the best accommodation to go for? Could we fit the baby into a four berth cabin with us on the overnight outbound sailing? What's best for the daytime return sailing - seat or cabin? If we go for a cabin, does that mean we have literally nowhere to sit down in the main part of the ship? It's all new to me - thanks for any advice!
