I didn't think 3-D was going to affect my impression of FJ, since I've ridden it Florida many times, but I stand corrected. I thought some, although not all, of the 3-D did enhance a few scenes. I do hope the Quidditch-style 3-D glasses do come in and that they work better with guests' eyeglasses. The Transformer-style glasses almost flew off my face a couple times, partly since they have to sit over my regular eyeglasses.
A minor quibble: Universal still doesn't think having larger locker facilities would be beneficial. Sure, they're not necessary, since it's been this way in Orlando since 2010, but it would have been a nice change in a newer building. In order to control over-crowding in the lockers, they've been queuing guests outside and letting the into the lockers in batches. It does help crowd control, but I wasn't expecting that, since in Florida, I'm used to going straight into the lockers--unless the standby wait is around 75 minutes (or longer, I don't exactly remember), then they need to control a queue outside the lockers. Here at USH, although I was using the single rider line, I was surprised that I needed to wait outside for 20 minutes (yesterday) and 15 minutes (today) before getting to the lockers and then going into the single rider line. Again, it's a minor point and maybe they'll refine the process over the course of the soft opens and previews.
Overall, I was impressed by the job that Universal has done with this land. This is a terrific addition to the park!
