I have a small bit of information on how the hotel's game play may work.
Disney's writing a handful of stories that guests will play in. Each story will contain many steps. (As an example from the movies, one story is Episode IV is "Escape from the Death Star", and one step in that story is "Disable the Tractor Beam.")
It would be bad to have families waiting in line to disable the tractor beam - you lose the feeling of being in the story. So you only want one family at a time anywhere near the tractor beam.
The problem is that you can't predict exactly how long it's going to take each family to finish the steps *before* they get to the Tractor Beam. That's because for good game play, you want to give them the freedom to take 5, 10, or 15 minutes to complete those steps - you don't want every step to take a specific, set time.
So you know that X families will need to visit the one Tractor Beam room. You don't know exactly when any of them is going to arrive. But you need to schedule them precisely and without conflicts.
It looks like Disney is going to solve this with two things:
1) You're going to have a "guide" who tells you the next step of the game, why it's important, and what you have to do. (It's your Dungeon Master - let's call it what it is.)
2) In addition to the regular steps in every story, the DM will be able to send you on any number of side quests that take a variable amount of time. These side quests will enable the DM to "buy time" before sending you on the next, formal step of the story.
For example, if your next step is to visit the tractor beam, but another family just went into the tractor beam step and it takes 20 minutes to complete that task, the DM will send you to find someone at a bar and ask them a question, and tell you to come back within 20 minutes so you can relay it via satellite to someone else.
This is a fairly complicated scheduling problem (it's
NP-hard, fam) and requires custom software to be written. Because of that, WDI isn't working on this part - it's straight from the PhDs at Disney Research.
