Yeah, I'm sure it'll be scaled down somewhat, though I'm sure the car will still fly, since that's like the whole point of the show. Maybe they'll do what the Phantom tour does and have two separate sets, so they can set up in the next city before the run in the current city ends.
I think I might check this out when it comes to Baltimore. The Hippodrome's certainly big enough for a show like Chitty.
