One of the more common 'complaints' about DAK DAH has been just how long the total experience time is for FoP... meaning, from the second you walk in the queue, whatever wait you have, the various pre-shows, the ride itself, and the walk out just takes a really long time. Also highly variable on if any levels are closed/offline/unstaffed. Reports have generally been 20-40 minute total experience times (20 being if you're lucky). If you're going for more then one or two FoP rides, I might be inclined to build in more time.
Curious to hear how it goes for you on 4/3! I have been pondering trying to find a way to go that night too, as I still haven't been yet!
