We always find it helpful to wear Aqua shoes. The sidewalks can be hard on some feet, and the sun can make them really hot. Get there early, find the place to put your things and go!!! It would be very helpful to get ahold of a map ahead of time, and decide what things you really want to do and what things you could do without if necessary. When we were at BB last August, some things we did right away because the lines get so long later in the day!
Good luck, and have fun!
