We just got back and decided to rent instead of bringing our own. We have DD9 and DS3. We were travelling with my sister, her DH, DS5, 4, 2. We each rented one double stroller, intending for the boys to ride. My DD9 rode as much as the boys, in fact, Dsis's DS5 wanted to walk the whole time. It was the best $80 we spent at Disney. We rented for 5 days so whatever $79.99 divided by 5 is was what it cost per day. A single one is a little cheaper but we saw hundreds of people who rented a double with one child wo they could put their backpack, souveniers, etc. We encountered too many people trying to get on buses with sleeping kids in their own strollers. The bus drivers will NOT let you on the bus without taking the child out and folding up the stroller. Same for the monorails. Strollers can be as big a hassle as they are a money saver. We have done both, home and rental and I would rent every time!
