We arrived at AK at 7:30, caught the tram and went thru the 'No Bags' security entrance and the AP turnstyle so we were inside the park by 7:50am. The area in front of ToL was filled with guests all facing to the left towards Pandora. About 8am, the mass amoeba began the migration towards Pandora. We got into the FoP 'line' at 8:05 and began the sluggish journey back towards FotLK. We were at the turn-around area for the line and the CMs there suggested we should be on the attraction within 3 hours. By 9:05 we made it to the actual queue for the attraction where the Stand-By sign suggested a wait of 180 minutes. We were inside the building by about 9:30 and spent 20-30 minutes in each 'room'. We reached the attraction at 11:15 and were into the pre-show video a few minutes later. The pre-show and actual ride was a little under 15 minutes total.
The sky was overcast early, so the heat was not oppressive and the outside fans did help with the comfort level. There were 2 men who tried to cut into the line by all-of-sudden appeared standing in the area the CMs were keeping as a walk-way. When it became apparent that they were moving as the line moved several suggested they not try to cut in line. They replied first with 'Its OK - we were here earlier' and followed that up with 'We have FP' - but they drifted back a few groups and finally assimilated into the line just before reaching the 'Standby' line sign (in spite of their non-existent FP). It takes all kinds.
FoP itself was wonderful - not worth a 3 hour wait in the future, IMO - but a truly creative adventure! The landscaping and theming enhance the experience. When we exited the attraction, the 'Standby' wait was 240 minutes and NRJ was 120.
We'll try NRJ on a future trip.
