It may be according to where you are staying. Our first trip, we stayed at the CBR and rented a stroller at the parks, because we didnt want to fight the stroller on the bus. That worked out real well. Our daughter was 2 at the time. Our next trip, we stayed at the poly and our daughter was 4 and little brother was 20 months. We carried to cheap fold up strollers, and it worked out great because we could load the kids in them at the room, roll them directly on the monorail, and transport them that way. You cant do that on the bus. So to sum it up, if you travel by bus, I would rent. If you can get there by monorail, go with small strollers. You can buy mesh bags and umbrella holders to attach to the cheap strollers.
