So to spend all the money buying one, the thought of plunking down $30 or more to rent one makes me queesy. But of course we've tried it. It was nice going from Magic Kingdom to then MGM not having to lug it around. But in all it wasn't too bad carrying around a compact stroller...
The only time I may rent one is if we are flying in, but quite honestly I don't see that happening while my kids are that young, so I spend zero dollars on rental and more on other stuff.
FYI - my kids are age 3 and 4.
It has gotten extremly expensive at WDW to rent a stroller now!
