Pricing is in there. As I mentioned, the organization of the website isn’t very good, so you kind of have to hunt for it, but basically goes back to the same source as @Padme501st posted.
If they can fit five into a regular deluxe resort room, which they do, I see no reason why they couldn’t in the SW resort. There’s no need to reinvent the wheel. Admittedly, it’s tight which is why we bought a Deluxe room at a deluxe resort last time.
Looking at the blueprints, there appear to be 3 sizes of rooms, with the first class suites being significantly larger than the other two sizes. I’m guessing this corresponds to the Deluxe room (like what we had at BWI), which does sleep 6.
I have. I am a little bit claustrophobic (hate spelunking for example, and really hate crowds). I think that the illusion of there being space outside would really help- as long as one isn’t agoraphobic, too. There is also the issue of motion sickness. Even if you’re not really moving, they’re going too make it seem like you are, and it’s that eye/inner ear disconnect that can make one sick. I don’t think I want to be the first family “on” this flight, for sure.
