Hi, Timothy!
Extra Magic Hours, especially in the morning, are among my favorite times in the parks of Walt Disney World. Everything seems to have a little extra sparkle and Guests are free to enjoy themselves before additional crowds arrive. I love it!
Typically, the most popular attractions are open during Extra Magic Hours, but you can find which attractions are available on the TImes Guides, which you can pick up at the Parks as well as at WDW resorts and Guest Services at the Transportation & Ticket Center and Downtown Disney.
