Is that wishful thinking?, cause it hasn't been the plan.
There's no way that garage will be big enough for VB, the hotel, and the convention center, especially when Sapphire is busy and/or there's a convention going on.
EDIT: Looking at the space that garage is going in, even though it looks like it will be 4 floors tall, I'd expect the capacity to be somewhere between Cabana Bay's garage and Portofino's. Likely closer to Cabana's.
Well then they're gonna be crap out of luck, because existing parking can't handle the theme park guests and WP guests, not to mention the bus area can barely handle Cabana Bay buses, let alone buses for the WP too.

I'd like to add that if they price this the same as their other "theme parks", it will fail miserably.
It won't.
