This is something that I have been thinking about when it comes time for me to bring my baby girl to WDW. Right now she is only going to be 5 months on July 4th and I am not thinking of taking her till she is around 3, but a stroller will be essential. I am coming from Massachusetts and will be taking a flight so my question is would it be better to bring my own stroller on the flight or should I just rent on at Disney?
