I just am still not sure what to do about strollers for the trip. My kids are DS4, DD3, DD1. We went to the zoo on a hot, humid day and DS 4 only lasted about 3 hours before he wanted to ride. Out comes 3 year old, in goes 4 year old etc. I really am worried the trip will be ruined by stroller battles. He is not going to want to walk all day, everyday. The problem is I only have a graco big old front to back double, a old graco single and a cheap flat folder that will not work. I am thinking about getting a mcclaren single so I can then use if for DD1 for the next few years. Then I would bring both the graco double and the single mcclaren. I think the disney buses will be a huge pain with the graco double, but I can't go out and justify two new strollers and I won't really be needing a double too often at home. I am thinking at least the mcclaren has the carry strap and my husband will have to deal with the graco but it seems crazy to bring two strollers. Renting would cost more than buying so that is out. Any recommendations? I can't figure out what to do but I am just picturing the 4 year old whining why can't I ride, it's not fair..this is supposed to be fun and I want to make it as easy as I can. This will be our first vacation in 8 years and based on our budget proably our last for a long time.
