It's been several years since my last trip to WDW, and I can't remember how we got the wrist bands for the EEM hours. Do you purchase them at the hotel or do you have to go to the park? Do they sell out? If you have to go to the park to get them, does that mean you have to go first thing in the morning, or can you get them later in the afternoon? See, we usually visit one park in the morning, take a short afternoon break, and then go to another park that evening. Thanks!
