We just came back from US/IOA we had a great 4 days there....WW was not so bad the first day we went, the line at Olivanders was only ten people in front of us and twenty in back of us. They still had a person outside controlling the line, there was a person in back of us holding a place in line for six others who came galloping up at the last minute and he promptly pulled them all off line and put them in back of the queue. Dont mess with the Wand people!
I have to admit, and Ill be admonished for this, but I didnt really care for WW. Other than the fact that my 10 yr old son was picked to get a wand at Olivanders, I didnt really see what all the hubub is all about. The FJ ride was really jolting, the castle was awesome, the mini rollercoaster was ok, and the shops were overcrowded and overpriced (all two of them). The line for butterbeer was short, and it was tasty, but you get to choose between a 10.50 plastic mug of butterbeer or a 3.50 plastic cup? I dont mean to keep harping on the pricing here, I can well afford anything sold in the park, but I felt a little ripped off at the pricing at WW compared to the rest of the parks. Sort of like a little tourist trap.
WW is a nice concept, but it could be expanded a little more and from what I read here and from what some park employees told me, they are in the process of doing that. They are also bringing over the Transformers ride from US California. I believe it is going to replace the Fear Factor area.
