So you don't think it's going to cost Disney more money by adding dedicated buses?I don't think anyone should be inconvenienced at Disney's prices. But if someone should be, a five-minute delay to get to DAK (which all of us experience) doesn't seem unreasonable to avoid a 30-minute delay for those going to the water park.
Personally, I'll make the best of it and book a Rainforest breakfast at 8:30 and then go to Blizzard Beach. But it's an inconvenience.
