Interesting few tidbits I've learned about FEA over the course of the last few days, so I thought I'd share what I could.
This may go without saying but the ride apparently wasn't even fully ready by 6/21 for opening. They hadn't finished all of their tests, but given what happened with RoL and PR in general lately, they insisted that it was going to open on 6/21. CM training was also rushed apparently, so they're still trying to figure out the optimal FP+ to standby ratio.
As a result of not having this ratio down, Disney has restrained itself a bit with FP+ distribution for this attraction (thank goodness, can you imagine if they hadn't!). According to Josh from easyWDW.com, they haven't distributed any FP+s for before 11am for this attraction from July 1 and beyond, so he says it's a possibility that some more may become available. He also put together a fantastic chart of wait times and downtime (that or when it was not accepting standby are in red) for FEA's first week (warning: not pretty). Here's the link to that.

Also, on a related note, I've heard from a number of solid sources and first-hand reports that Disney has been playing with grossly exagerating the posted standby wait lately. This was not the case over the course of FEA's first few days of operation, but I've seen quite a few reports from different times and days over the weekend of waits being posted of 180+ minutes and standby guests finding actual waits to be blow 45 minutes. I guess the goal here is to keep it open so it remains an option for people so they don't complain but to keep the wait so high that most people balk at the posted wait and do something else. Not saying that a high posted wait at FEA guarantees a much shorter actual wait but if you're willing to take the risk, it might be worthwhile. Not sure if this is something they'll be continuing though, so I'll keep everyone updated.
