Love, love, love my Maclaren Volo stroller for theme parks, the zoo, etc. This stroller has been to WDW for 8 multi-day trips, plus has made it through six years and two kids at many, many events and outings. And it is still going strong. Best $100 I ever spent. (I've given away all of the other strollers.)
It folds easily with the push of one foot and the pull of one hand in one little swoop (VERY important when you are trying to get on the resort bus with a sleeping kid in one arm while trying to hang on to another kid AND fold the stroller at the same time). And when you are on the bus, it tucks out of the way easily, which is also important when you are trying to hold on to two sleeping kids and a stroller and the bus is packed.
