We (me, husband and my two boys-ages 3 (just turning) and almost 6). We have never flown with the kids. I would like to take my own stroller so we don't have to rent one at WDW and I would like to be able to use it in the airport. How does that work since you aren't checking it in as luggage? We also plan on using the Mag. Express. Will we be able to bring it on that. The one I want to use is kinda big (not huge), but it has a cart of the bottom (I want this for drinks and stuff). Any suggestions?
