Do not underestimate the amount of walking that you will do at Walt Disney World! I spent a full day at Epcot the other day and I ended up walking 35,021 steps. That’s more than the distance for a half marathon! I’m an avid fitness walker, but I still felt this at the end of the day. It’s never a bad idea to increase the amount that you walk leading up to a Walt Disney World vacation, and make sure that you wear comfortable shoes that are broken in.
