We are looking at being at Universal this December. Universal's site talks about the Harry Potter projection show and the Christmas version of it. I read some reviews of it this last year and it seems really cool. But it also seems like for most of December the parks are only open until 7 which isn't that long after sunset--Touring Plans actually indicates that the show wouldn't be on for most of our trip because there isn't enough time between sunset and park close. Surely that's not actually how it works. Can someone tell me how it worked for Christmas this last year?
