Just returned from EOS on 3-nighter to St. Thomas and St. Maarten (2/27/06). I stayed in room 9174, which is to the rear of the ship. You apparently have a balcony room booked? I spoke to a woman who had a balcony on this deck and she said it was small, but adequate. Your room is towards the centrum part of the ship, but still towards the rear section and on the opposite side from where I was. You don't mention where your trip originates from, but I am assuming that it is from San Juan.
