Sneakers

On vacation I try to dress the kids as cute as possible.  Really, when are you going to take as many pictures as you do when you're on vacation?  Out come the adorable sandals, cute dress up shoes, etc.  But when you're in Disney you will walk A LOT!  You and your kids - even if they are in a stroller most of the time.  Flip flops, sandals (even the super cute ones!), princess dress up shoes (because little girls have to match their dresses right?!), etc. are not a good idea.  You will most likely be walking miles...yes, miles each day.  Walk to the bus/car, walk from the bus to security, security to all the attractions, stand waiting for the parade/fireworks/show/etc., and then walk back to bus/car, and back to hotel.  Almost every vacation I drag out the flip flops and attempt a day with them.  It's Florida and it's hot and I don't want my feet covered!  But it's a mistake...every time.  So get a nice pair of sneakers and workout socks work wonders.  Your feet will thank you!
Oh and if your son or daughter "insists" upon wearing the super cool flip flops or have-to Cinderella heels, pack their sneakers and socks in your backpack.  They'll thank you for it later.  And you won't have an exhausted, in-pain child on your hands.
