Time to try Teva. Definitely don't want blisters. Is it true you end up walking 6-8 miles per day. UGGHHHH!!!
Actually, I recently saw a thread from a guy who tracked it with a pedometer, and it consistently registered 9-13 miles per day!!! Yikes! We have a little more than 100 days until our trip and I have GOT to start taking the kids on Disney Walks if that's the true average.
