I really liked HPW, its just, it was WAY too crowded for my likes. I mean sure, they made everything in the books come to life, but they really should've taken into account the crowds they draw. Its still a vivid memory in my head being gridlocked in Hogsmeade, finding there to be a 3 hour wait just to get into the Three Broomsticks after enduring a 2 hour wait to get into one of the gift shops. Luckily Honeydukes was only a half hour wait, and all the while, the stores' interiors are SO small its ridiculous.
That said, FJ is so well detailed, organized, and immersive that it mostly makes up for what I'd consider poor planning crowd wise. That and the butter beer, oh boy that was delicious. I'm not trying to bash HPW, I appreciate their detail and loyalty to the books to scale, its just a scale replica doesn't really meet the needs of something that draws SO many people. Now don't get me started on IOA's system for distributing HPW passes...
