OK, after close examination, here's my take:
The "Play" Pavilion is going to be like when in Ralph Breaks the Internet, Ralph and Vanellope visited Oh My Disney website. And so, entering the pavilion, you'll be transported to various Disney web apps/sites.
As far as the interior design goes:
- there's a sunken mini-ampitheater facing a stage. Looks like there are dancers and Vanellope and a guitarist on stage
- the light globes all have circuit board designs... again, signs we'll be in the internet
- the sky is a star field (I hope that will lead to an active one with cool projections)
There are characters walking around:
- Mickey
- Tinkerbell
- Vanellope
- Olaf
- Sleeping Beauty
- Nick
Whether they'll be M&Gs or walk-arounds or even there at all is unknown. Obviously, there won't be a four inch Tinkerbell buzzing around you.
There are two characters represented as toys being held by a child
- Plush Mickey
- Buzz Lightyear
Then are the building frontages going from left to right:
- Edna Mode Emoji
- no other text, so, maybe it's an Edna or Incredibles M&G?
- or maybe an interactive costume place with touch pads to create costumes or mirrors to overlay costumes?
- Dance Dance
- at least, that's what I think the sign says
- there are three dancing characters on the sign
- there is a colored wall of blocks similar to a Candy Crush game
- so, either its probably a dancing game place, or, just has a dance floor with lights as in the disco floor of Staying Alive
- Cinema
- emoji of Marie on the front
- what looks like a big "D" at the top of the tower... wonder what that could stand for????
- And a big play button at the ground floor
- so, guessing it will be a place to see movies, shorts, cartoons, etc...
- Let's Play with Exclamation Point icons
- maybe some sort of gaming room
- Wedway
- nothing of note on the front of the building, but coming out of the right side is a big tube on the ground floor and the monorail above it
- a demonstration of motion, or and actual (kiddie) mini-ride?
- Hotel with sleeping Joy emoji
- I'm guessing a nap place or quiet lounge
