The park strollers are great if your children are past the infant stage. The wheels are bigger and much easier to manuver around the parks. They are hard plastic at MK and Epcot, I think. The ones at MGM are more like joggers. The pictures at wdwig.com will help with the specifics. The plastic strollers are more like carts, plenty of room for the kids and easy for them to hop in and out of. My children will be 2 and 4 when we go in Nov. Instead of a double, we are going to rent 2 singles. My 4 yo DD will want to walk in the mornings and we will rent a second after lunch. My brother rented a double our last trip and found it very hard to manuver through a tight crowd- like leaving the parks at closing time. Also, if one child is sleeping and the other wants to ride, you can split up if you have singles. Just something to think about. Either way, you can't go wrong with the Disney strollers! They are so convenient!
