I'm seriously considering renting a double stroller for my 6 and 8 year old to use when exhausted to decrease the whining that I KNOW we will get- even if only for a larger park. I admit, tHis kind of seems a bit old for them but a few years ago we rented a double when they were 4 and 6 and I think I remember the the 6 year old resting in it occasionally when tired. Last time we went in late July and it was sooooooo hot. We are going in early June so maybe it's not so hot. I'm also thinking pushing around a stroller might be nice due to it can carry around our backpacks. The heat was horrible in July and I remember it zapping so much energy out of our kids. I know this all depends on your children but I would like to know if anyone else has done this. My kids are not lazy by any means but when it's really hot.... I guess the real issue is the whining. My kids will be able to walk the parks but the whining? I'm thinking probably not. I think rest breaks are going to be enforced... and perhaps Tylenol. I know if you've ever been to Disney you've seen families get "Dised out." You know, the cranky whining kids and the mom who looks like she just can't take it anymore. I don't want that to be me! I did edit this post for clarification.
