Our last trip, we went to DTD two or three times and I honestly dont remember ever seeing anyone with a rented stroller. They're big and pretty hard to miss and always seemed to be headed right for our ankles so I'm pretty sure I would remember some stroller dodging while we were there. Plus, the double strollers that they rent are pretty big, and it wouldn't seem to me that they would fit into the stores between racks too well. That said, I would definitely bring a stroller with you so you can enjoy some great shopping!
