We were there too, I am pretty sure they were flying ants. Not carpenter ants, but male ants with wings, only come out a few days a year and they come out in massive swarms.
When I saw the single use kiosk a few weeks back I was kinda irked but really since then I've not seen any marked difference in FastLane wait time so I'm pretty indifferent to it (I have all season FL and pretty much go with my kid every weekend). To be fair though, I avoid FoF in general b/c 1) FastLane takes forever compared to every other single ride at KI and 2) Even if FL was not slow the ride just isn't that enjoyable to me.
Any word on The Beast? It was down Tuesday and Wednesday, I just looked on the app and it still says Down.
What's going on there, it seems to be having a lot of issues so far this year.
