Personally, I don't get the excitement behind this. I understand people are happy to see something being done with the abandoned legendary years, but beyond that, I don't get it.
This isn't something new, it's not as if Disney has finally solved the 5th person dilemma. Unless I'm mistaken, this is just going to be like the ASMu family suites but on a larger scale. It doesn't create a solution for the people who do not want to stay at a value but have larger family.
Disney already had the affordable suite options, and they also have the other extreme, which are expensive suite options. What they still don't have is an option in the middle, unless you include the trundle bed rooms at POR which IMO aren't exactly an option if the fifth person isn't a child.
The theme is also disappointing, at face value it just seems like an extension of All Star Movies, and Nemo already has themed rooms at the Caribbean Beach. Also, I don't like the fact that it's "connected" to Pop but the two themes don't really match.
Sorry for being a downer, but that's just my two (or maybe more) cents.
