On Sat. 12/18, we went to US/ IOA at 2:00 when the rain stopped. The parks were empty! We walked on all rides (several times)...had a blast! We toured the Wizarding World with no waits. FJ is extraordinary and the theming is top notch! However, only in low crowds! Last night, entry to the HP section of the park was absolute chaos with very angry guests! Today, we got a ticket to return the area. The wait times for FJ were 150 minutes. Lines for the stores, vendors, etc. were very, very long. Staff/ security were yelling at guests as there were wall to wall people. IMO, Universal has some work to do to help ensure the safety of their guests and to inform them of the procedures involved in visiting this area. Our family has never read a Harry Potter book or seen a Harry Potter movie. But, I was heartbroken for the families that traveled to see this area of the park only to be nearly trampled over a wand or scarf.
