I bought a Peg Perego Aria Double side by side online pretty cheap. DS is 5 and DD is 4. It is lightweight (only 14 lbs and folds easy) and you can carry with one hand when folded. The seats recline and the footrest is not as high as most, so my kids are pretty comfortable. I have taken it on two test runs to the mall and my kids love it. We bought it for our trip in Sept (9/3-9/9) and will be selling upon its completion. We bought for 200.00 and plan to sell for $100. We got it off of Albeebaby.com
We figured it would be nice to have our own instead of rent and after we sell, we will be out about what we would have spent to rent.
