I got to ride both rides last week and loved every minute of being in Pandora! We had FP for FOP so we went to Navi at rope drop. I enjoyed the river ride. I know a lot have comments have been love/hate. The FOP is absolutely amazing! I had been trying to avoid a lot of pictures and descriptions so I would be surprised. I totally was! My son and his friend were able to ride twice and he said the second time was even better. I would totally wait in line to do this again, not 210 minutes but definitely 60-90.
My only complaint is one of the seats was broken (ok it happens) but my mom got moved so she didn't sit with us. Come to find out, there were three more empty seats in the next bay! They could have moved all of us together AND get a few more people on the ride. Seems like such a waste when so many people are waiting. I also think they could cut the pre-show in half, way to long.
For those worried about the seats, my husband didn't fit and I had to have a slight push from the CM. My husband is all stomach at 350 pounds, 5'11. I'm all rear end at 5'9 300 pounds. I totally get why they have the back piece to help lock you in but it absolutely could be adjusted/changed slightly so people of size don't have to stress. My husband and dad both tried the test seats before getting on. No one payed any attention to them and the CM was super nice.
