They want you elsewhere spending money, not standing in line.I was wondering this as well - we’ll be there in July for the first time in nearly 3 years and knowing that there’s no guarantee we can get on this ride is going to make the morning of an Epcot trip very stressful. The silly thing is, as we’re travelling from the UK, we would be quite happy to queue all day long if we had to, to try this ride at least once.
A standby queue naturally filters out the guests who feel their time is better spent elsewhere, but this system means there is no reason not to try to get a boarding pass, and the more chances you’ve had to do so, the better you are at the process. I would’ve thought this would be pretty bad for guest satisfaction overall… I know we’ll be upset if we can’t get a boarding pass during our trip.
Also long lines cause logistics issues elsewhere in the park, and the front of Epcot is hardly a wide open expanse right now. VQ was a given. The only question for this one is if, because it's VQ, they'll greatly shift the balance of IAS/VQ to the IAS side of the bracket.
