We just returned today. I agree...Friday was, by far, the busiest day during our stay. Wed and Sun were the quietest. Early entry will help you immensely. Take advantage of it to check out Olivanders first thing if you are at all interested. It's a cute little wand "show" that takes about 5-10 mins and exits into a small wand shop. If you decide not to wait in line for the show, there are other places to buy wands other than Olivanders. Then go ride Forbidden Journey. During our stay we never waited longer than 15 mins to ride FJ (or any other ride for that matter), and rode several times. However, there WERE 60 min wait times posted for FJ, at times, on Fri.
