On the nights there wasn't a quiz or game after dinner, or it was one we didnt feel interested in - then we took a cocktail or a coffee and watched TV to wind down after tea - like we do at home.
We took a fire-stick with programs loaded from home, we didn't watch anything on the TV channels there.
We sat with different people not set dinner companions.
One night DH wasnt feeling well and he had room service for dinner - bit squashy but room enough in the cabin. For one person at least - I still went to the dining room.
Some people regularly had breakfast in their cabins or on their balconies - we never did but we saw breakfast trays outside other rooms.
