I agree with Pterosaur's that it is extremely frustrating. If there aren't as many open hours as there used to be for maintenance, profit reasons, etc., fine, but just decide it sooner. We have to plan everything else out so far, make FastPasses, dining reservations, etc., it's difficult to do if the hours aren't clear. It's also very frustrating when the hours change in a way that would make us alter our plans on which park, dining, etc., but the only way to do so would be to abandon a couple days of FastPasses because we made them a month earlier based on different hours.
