Quoting LolaMcKitten:" I'm thinking that with all the kids, simply having the extra storage space might be worth it when we ... [snip!] ... worth it when we DO all get to go out....we'll still have 2 diaper bags and we usually have a cooler or bag with snacks......"
i have the graco duo glide and theres tons of space underneath. Perfect for trips to the mall, the zoo, or anywhere else where you need something that will serve as "home base"
I prefer the kind that have one seat in front of the other (rather then side by side) just because it fits through things more easily that way.
