I thought for sure they'd use the arcade structure just because it was already there and it might be cheaper than a new building. Guess Oddball lives. The funhouse structure in this site plan seems to be a near exact match to Fiesta's funhouse dimensions.
As for queue design it looks like the funhouse would primarily be optional if they decide just not to use it on low attendance days or if something needs fixed in there, that or a bypass for those sensitive to strobe lights (not sure if those are used in Fiesta I haven't looked at a walkthrough). And looks like there will be plenty of switchbacks to hold a good number of guests, even more than Fiesta has.
My biggest disappointment with this orientation is it is turned 90 degrees from my earlier mockup. So rather than a beautiful angle of it swinging over the Brittania game building as you walk back to the area you'll just see it from the least interesting angle (IMO).
PS: Supergirl. Not Wonder Woman.
PPS: Not complaining but NOT calling Rookie Racer Kid Flash when it'll be RIGHT NEXT to Joker and Supergirl kinda seems like a missed opportunity now (I like it when original names are used, just saying from their perspective it seems like something Six Flags would normally do).
