Apologies in advance for this "newbie" question! I'm booked for a 14-day sailing on Sky Princess in October/November. In the Cruise Planner, I only see a 14-day single pass to the "thermal suite" available. Is this the same as the Enclave? Will more options (such as a single-day pass or 7-day pass) open up closer to the cruise? A follow-up question: All I'm really interested in is access to a sauna and/or steam room (which used to be complimentary on the older Princess ships when I started cruising). Is purchase to the Enclave my only option on Sky? Thanks so much!
