This is our first Disney cruise so we don't have any priority when it comes to booking. By the time I was able to get in and try to book spa appointments, the massages were all booked for the times that we weren't in port. Do they open up additional appointments once on board? If not, do they create a waiting list or anything in case other people cancel? Luckily, I did get a pedicure appointment, so at least I will get some spa time!
