Starting to seriously research the Galapagos.  Been wanting to go for years and thinking it is finally going to happen within the next year.  I rarely care which ship I am on, but, I see there are three ships with Celebrity - 100 passenger Flora, 48 passenger Xpedition and 16 passenger Xploration.  I am curious which ship you chose and why?  Did you like the ship?  Also, was there a gym onboard and did you have time during the day to use it?
