I don’t think the Orlando parks could go 5 days a week. There’s still people flying into Orlando for vacations...or at least Disney/Universal are dreaming there are.My prediction: September is going to be the lowest attendance per park that UOR or WDW has seen in decades.
I would have never thought 5 days would ever happen, but considering they’re suddenly regional parks, it’s entirely possible (six flags already moved to 5 a couple weeks ago).
I just don’t know which days of the week you could shut down while keeping trips for out-of-towners viable. You definitely can’t shut down on the weekends. You can’t shut down Monday, Tuesday, Thursday or Friday because you prevent people from taking 3-4 day long weekend trips.
I guess you could close on Wednesdays?
