I miss IASW and WWPM being a walk-ons! FP+ has inflated all the SB lines.
Although some claim that it will be used at DLR, that's not going to happen. At DLR they will charge guests who want to make same day FP reservations via their phone, but the machines will still be in the parks.
FP+ works for some people, but it becomes increasingly cumbersome if you're trying to link reservations or book rides for large parties. IMO, it's a joke when this "technological marvel" is incapable of springing forward by 1 hour.
I also think the Shanghai isn't to blame for all of the upsells at WDW. If that was the reason, why aren't there just as many at DLR? I think the upsells, F&B, and merchandise increases allow Iger to pretend that MDE was a terrific investment. After all, MDE was supposed to drive people away from the attractions and into the stores an restaurants, but this hasn't happened.
