i like wide sneakers. your feet will swell and you'll be glad you have the extra room.
I like Sketchers, and they sometimes have some cute embroidery on them.
Do yourself a favor. Start walking now. My son and i do about 5 miles a day at EPCOT.
It's the best park there and make sure you hit every exhibit. they all seem to have something
hidden inside. In The Land, they have soarin. it's a wonderful ride, and make sure you try it.
Just walking in the park from the lot can be a mile. bring water. ALL restaurants give out free water.
have fun.
