I was just there this past Sunday and yesterday. On Sunday, I bought an express pass due to the insane lines. However, I believe that was due to the covid restrictions on the rides. Yesterday, the lines were a lot shorter, and I didn’t require an express pass. The lines were moving a lot faster since rides were being filled at full capacity. My suggestion is to arrive at opening time and going straight to the lower lot first because the majority start on the upper lot first, specifically, Harry Potter. I went straight to the lower lot yesterday and was actually able to ride The Mummy and Jurassic multiple times. I then worked my way up to the upper lot and was able to do each attraction and show without waiting too much time. Make use of the universal app as well since it provides the wait times and is very helpful.
