Stand by lines for both FoP and Navi river are both long,you need FPs for both.FoP is always going to have a longer wait but I rather stand in a 2-2.5 hour line for FoP than a 1 hour line for Navi river,the Navi queue is boring and the ride is nice and cute but its basically a 3 minute boat ride.FoP has a more interesting queue and is a great ride.I've ridden FoP stand by 5 times and waited 125,110,130,120 and 55 minutes.Also rode it twice using FP,Navi I've ridden twice,55 minutes standby and used FP the second time,obviously I have no issues with the standby at FoP.
