I was at both parks 3 weeks ago (2 days at KI, 2 1/2 at CP). Seems like ride ops had mostly hit their stride and everything was running really well, besides Gatekeeper obviously. In fact the only downtime I recall seeing on TTD in three days was a couple of times when weather brought the whole park down for a few hours. We didn't see any significant downtime unrelated to weather at either park, besides Gatekeeper which had the broken chain. Rides were opening on time and lines staying open past closing. We usually visit late May or early June so this was a nice change for us.
FL+ was amazing at both parks. It always is at KI but we rode Steel Vengeance 11 times and never waited more than 20 minutes (usually more like 10 minutes), even when the standby line was posted at 2 hours. In fact, I don't think we waited more than 20 minutes for anything at CP, and most things were more like 0-10 minutes.
Food service was pretty hit or miss at CP. Miss Keat's was understaffed and insanely slow, but Melt seemed fine when we went. We had the drink plan and didn't have any significant waits for those stations. I don't recall having any food service or drink issues at KI.
Maybe we got a little lucky, but overall we had a great time at both parks.
