The red ones are the new ones Disney has now, but they still are not comfortable and are unable to lay back, I rented a City mini double stroller from a stroller rental place called SIMPLE STROLLER RENTAL and they were great. The Height max was 47inches but the kids were a lot more comfortable then the Disney ones that are a hard plastic and cramped. You pay a lot more for the ones at the parks and they have to stay in the parks. The younger one fell asleep in the stroller and we were able to push the stroller to the other transportation and car with out having to wake her up.
