Help, I so don't know what to do. We are going to Disney 2/23 to 2/29 with a 6year old and a 21month old in a leg cast. I have a pretty nice umbrella stroller (not the real cheap ones). Should I bring my own stroller for the parks or should I rent one. One friend told me to rent a double so the 6 year old can use it when needed. I think thats a good idea, but it is dumb to spend almost 100 dollars on a stroller when I own one?? Please give me advice.
