I will be taking my 7yo DD and 3yo DS next week to WDW. I know she will walk most of the time, but will get tired of walking. I have not really budgeted for the expense of renting a double stroller. My husband is not going to go this time and I can't push 2 strollers by myself. Also, the kids will not want to ride together!!!!! She has been to the World several times, but has never walked. Do you have any suggestions??? She is very tall for her age and weighs more than the 50 lb limit for a jogging stroller. Any help will be greatly appreciated!!!!
