At first, it feels a bit silly to go there for only half a day (I had to leave by 13:00 sharp), but I figured that by being efficient I could see most of the park by that time. To help towards that goal, I bought the skip 5 lines pass, and sure enough was able to do all the attractions that mattered by 12:45 (I'd have missed a couple but 2 were closed, so it worked out). Some attractions like backdraft and back to the future are exactly the same as universal studios in Hollywood, while others I hadn't seen before, including the brand new Harry Potter movie/ride combo that people lined up 2h30 to see. Thankfully with my pass, I only had to wait 10mn to get in. I arrived 30mn before the park opened and it was a good idea because plenty of people showed up too, and thankfully I was close to the front of the ticket buying line. Once in the decors were quite nice: Some rides were ride/movie combinations where the blend wasn't bad at all actually: Spiderman 4D: Back to the future: A few rides:
150mn wait for the new Harry Potter ride
Hollywood Dream, the ride was an ok roller coaster, but not worth the normal line
this fast-ish train gets you to the airport in fewer than 30mn
