During the day I like the Ocean bar area. There are quiet nooks with windows looking out onto the praminade deck and the sea beyond. A great place to read or just veg. out. An excellent place to hide. The explorations cafe is essentially part of the crows nest (or vice-versa) on the Westerdam, so reading can be challenging if easily distracted, and besides that's the first place annoying relatives would come looking for you.
