We were at Universal 12/19 thru 12/24
12/19 Low crowds wonderful. Rides averaged 15 minutes except for Spiderman and Posiden which were around 30 minutes. We had FOTL and all rides were walk on.
12/20 Again Low crowds and wonderful. Much like the previous day 10 to 15 minute wait times tops, 30 tops for the more popular rides like MIB and Spiderman but again FOTL was walk on and we never had to wait.
12/21 Yet again Low Crowds wait times were creeping up tho' about 30 minute wait times and the more popular rides were 45 to 60, Spiderman in particular hit 60 minutes but with FOTL yep you guessed it walk on
12/22 The Day the crowds showed up. Everything hit 45 to 60 minutes + with FOTL most everything was walk on. I think we waited maybe 10 minutes to get on Spiderman and that was the longest wait of the day. It truly is how you time it though because after we waited in line for the 10 minutes to board we turned around and went again and didnt wait at all.
12/23 Crowds seemed to thin a bit from the previous day but it was still crowded 30 to 60 min wait times for most rides and with FOTL it was back to walk on status or if we waited it was never more than a couple of minutes.
12/24 The Crowds showed back up everything hit 60+ as this was our last day we hit our favorite rides again spiderman, MIB, Jurassic Park etc and with FOTL again everything was a walk on or only a few minutes wait.
The longest line we stood in the whole trip was Petradon Flyers at 30 minutes and thats because it's one of the only rides in park that doesnt have an Express Pass line. While DD loved it DW and I both agreed it wasnt worth the 30 minutes we waited in line. The only reason we only waited 30 minutes is because we got to the park early and we headed straight for this ride. We checked a few different days and each time the wait was will over 60 minutes and at one point it was 90! No way the ride is worth that kind of wait even with children.
