and only using the stroller for WDW, my recommendation is check your local craigslist.org for a used Graco stroller. I have one (lite rider I think) that seems to just not want to die. My dd is 8 and weighs I'd guess close to 80 lbs now, but I had absolutely no trouble using it when she was 5-6-7 years old (she is not a small child-weight was up to 70 lbs for sure).
It has a huge basket and folds up nice and flat. Bought it used and paid hardly more than $25 for it and it keeps going and going.
I also just recently bought a maclaren quest because of my ds3 and although I don't technically need it (because my workhorse of Graco stroller won't die), I wanted to treat myself (and maclarens have good resale value).
So you don't need a fancy stroller to get the high weight value. I find that my graco pushes just as easily (dare I say it) as my expensive maclaren quest.
And because it was cheap, I don't worry about any scratches or how much I use it or how well I take care of it. I know I won't resell it, so I just use it. Hope this helps you decide.
