This is pretty important if you are planning to visit Walt Disney World for more than a weekend. You want to plan a day in between your visits to the theme parks to take the day off and just relax. Sleep in, go for a swim in the hotel pool, or explore what all Orlando has to offer you. If you try to go to the theme parks every day, back-to-back-to-back, it will wear you out. You won't necessarily feel it on the first or second day, but I guarantee by the third day you will start to feel fatigue. Why is this important? Because i have found that trying to squeeze every dollar out in spending time at the parks has a negative effect. Visiting the parks becomes less like a vacation and more like a chore. The fatigue of going four or five days straight can actually ruin your vacation. I recommend planning at least one day off for every two days at the parks. If you can do it this way, you will have a much better vacation
