We expected the park to be busy but we were not expecting there to be LOADS of people.
We could barely move in The Harry Potter section, which made the experience awful. I would much prefer visiting the set in London than come back.
We were shocked that the lockers (which you had to use for some rides), charged. They are only $2 each but it soon adds up if you are riding multiple big rides. The VelociCoaster was the only one that had free lockers, which just made the experience so much better.
After spending time in Disney and Universal, it feels like universal are trying to get you to spend, spend, spend (lockers, express pass etc). It’s a shame because the rides are incredible, especially if you enjoy big rides, but the volume of people, lack of space and expense ruin the overall experience.
