Bought a Multi-Pass on the 19th, 21st, and 23rd for Hollywood, AK, and MK respectively. Got to the parks later in the day around 11am but still got the rides I wanted with not too much refreshing and I'd get on fairly quick as well. Definitely didn't take any longer than 8-10 minutes from initial tap point to getting on.
Edit - And on the days where I didn't buy a Multi-Pass wait times weren't as long as advertised. Runaway Railway was advertised as 45 minutes but got on the train in 20 and 35 minute Jungle Cruise was maybe 10-15?
