I know there are a lot of FP haters, but I reserve my opinion until I actually use it myself....but here are two things that hit me while reading several pages of this thread...
1. Its a new system. Disney has had several years of historical data to be able to determine how many on average use of FP- tickets of each day, holiday, weekend that they can fit "X" number in each hour. You cant compare systems this early on, especially while they are still testing it.
2. The new system is more convenient, all you need is a smart phone or have setup your reservations before leavin...in past you either had someone run across the park or come back...I would do a fast pass maybe once a day if that...with the new system, I would be doing the max since I dont have to run or come back to a ride at a later time. So you are having more people than the regular fast pass hitting this thing.
I seriously doubt that Disney would leave the FP+ lines at 30+limit wait and "call it a day". They are still testing, fine tuning and improving the system. It would be an epic fail if the system doesnt diminish the wait times, this will NOT happen, I guarantee it.
