Big change in May hours at IOA this year. In past years, short of Memorial Day weekend, IOA closed every night between 6 PM & 8 PM. This year they're open till 10 PM most of the days in May, with the Hogwarts show after dark. I'll be at the parks in a couple of days and we're really looking forward to enjoying IOA in the dark for the first time for more than just a few minutes. Kong & Hulk & JPRA& Camp Jurassic should be great attractions in the dark, plus the beauty of all the lands lit up. .
