I was able to book & prepay the thermal suite BEFORE our cruise   Big Smile.   In the past we had to wait til we either got onboard, or if they had a table set up in the terminal we could book there.     And, we saved $20/ pp by booking and paying in advance.  Cost was $179/ pp for the week.    I can feel those tiled warming lounges already. YummyYummyYummyYummy
