3. Wearing the Wrong Shoes
Magic Kingdom is a huge park. What this means for you is 1) a whole lot of fun, and 2) a whole lot of walking. Since walking in a pair of cheap flip-flops is never comfortable for very long, it is important that you bring along a comfortable pair of shoes.
Make sure they will be comfortable for the entire day and won't leave you with a collection of blisters to tend to later.
