I was planning on taking my Graco metrolite stroller to WDW in October, my son will be 18 months. After reading some other posts, I am wondering if I should switch to a smaller stroller--I was thinking of the Combi helio or flare stroller (it's more of an umbrella style, but has a reclining seat and a basket underneath. Any mom's out there that have traveled with the Graco, my concern is getting around on the buses and having to fold it up.
