We use the Jeep Stroller from Babies R Us. It is heavy and bulky - but it is the BEST stroller for traveling or shopping. Why? Well, my son LOVES to be in it - so that is a big plus! But also, it has lots of storage space to help carry things (great for lugging everything through an airport) - it has a built in steering wheel so that my son is occupied with toys that won't fall off and get lost and it can hold a ton of stuff - great for shopping trips or the airport. But it does weigh 28 lbs. and it is very big - so won't fit in most car trunks. My husband has an SUV, so it fits in there fine, but when I take it in my car, I have to put it in the front seat b/c it is too large to fit in the trunk - but totally worth it!
