Last year, we did Early Magic Hours every day of our trip. It was great. It was during spring break (peak season). At MK, we were able to do Pirates, Aladdin's Magic Carpet, Splash Mountain, Haunted Mansion, BTMR, Philarmagic, and Pooh in 2 hours. After that crowds got really bad, so we used our parkhoppers to go to another park. It worked out really well. I would definately do Early Magic over the Late entry hours. The option of staying up late is definately more appealing than getting up early.
