I love my Britax B-Agile and I brought it on our last wdw trip.
Disney trip pros: Fits in all doorways, smooth to push & steer, storage space, full recline for napping and very large sun shades
Disney trip cons: Did not fit in all store aisles (I'm a big shopper at the parks & DTD), folds easy but was a pain getting on & off of buses entire trip (I ended up standing with it folded on buses most of the time while my mom sat on the bus with my kids).
I'm debating on taking it our next scheduled trip. I may just bring my single Chicco Liteway stroller and another single (not an umbrella though).
