I don't really see how you are any more locked in with the new system than the old. Either way you have a set return time for the ride you can use it or not. If anything the new system is more flexible because you can change your time or even the attraction. Couldn't do that before.
And I've yet to feel a need to be glued to my phone while I'm there. Usually I make any changes on the bus ride over or while standing in line. It never interferes with my day.[/Q
With the old system, only the E ticket rides had FP. You could ride most attractions standby. I could decide wether or not to ride or move on at the spur of the moment. Now ,most rides have longer stand by lines because there's a FP line. IMO spontaneity is gone. I'm glad you enjoy all the planning, I don't.
