I had read the same you quoted, but of course PCL did not publish that they were ruining the rest of the Sanctuary for the steerage guests.
From the main video provided to date, it makes perfect sense that a Suite guest can come and go as the please and use the entire space.
What we do not know is if they show up expecting to use one of their padded loungers, and they are all full, will they be able to plunk down onto a sun bed lounger to wait for one to open up?
The Sun Sanctuary must have some capacity control, but that doesn't mean everyone gets a lounger.
IMO, we need a detailed report from a guest who interviews the Sanctuary manager and asks them a list of questions on the operation. Until then, I think we have speculated the heck out of the place. In fact, I have been thinking that the Sun Sanctuary needs its own thread topic and all posts in this thread on the subject should be moved to it. ( @Host CJSKIDS, is that too much work now with maybe 100 posts on the Sun Sanctuary- what do you think?)
