NGE is falling apart at the seams. Many of the executives who had been putting on a brave face and walking the line are now more openly pessimistic. Some of the enhancements will be nice but almost all of the revenue generating elements are crashing and burning.
I can definately see this backfiring. I am taking part in the test later in August and thanks to FP+, I will easily be able to shave off a few hours of park time each day.
Here is a typical schedule that I would follow:
Epcot: Arrive around 2:00 or 3:00, get FP for the future world E Tickets, head to WS around 6 for dinner and drinks
Epcot + FP+: Arrive around 4:00, ride E-Tickets, back to WS at 6
MK: Arrive around 4:00, start collecting FP for E-Tickets, Wishes, Leave around 11:00
MK + FP+: Arrive around 6:00, ride E-Tickets and others, Wishes, Leave around 11
DHS: Arrive around 10:00, start collecting FP for E-Tickets, grab lunch, leave around 3:00
DHS + FP+: Arrive around 10:00, ride E-Tickets, leave around 1:00
Do I like this better? Yes, absolutely. I will have more time to rest or spend doing other things but I don't see how this helps disney. I realize I am not the typical visitor (AP who visits 4 - 8 times a year), but this seems to stop me from impulse buying. If I am not waiting around for FP to become valid or waiting in line, I am just going to leave earlier or arrive later.
I also see this as a big problem with perception for first time visitors at the non-MK parks. If a first time visitor arrives at epcot and has the main E-tickets covered by FP+ before noon, they could easily percieve the park as lacking in attrations and feel bored.
