I'm going on my first cruise in 17 days and have a couple of questions especially since I'm cruising solo. 1. Rebooking - If I rebook onboard, do I have to tell them how many will be in the room? If I say just me, can I add someone to the room at a later date? 2. Palos - I'm not going this time as I want to experience the three restaurants on my first one. But I still have a question. As there is just one person in my room, can I make a reservation for 3 or 4 and then invite people I meet to join me? 3. Fitness - I'm curious about the metabolism thing you can do at the fitness center (cost is $30 I think). Has anyone done this? If so, what did you think about it? Thanks for your help.
