I have a BOB Duallie that I dearly love and have used constantly, but for ease -and the one I have used the most -it has to be the Maclaren Volo! Umbrella, lightweight, durable (and I mean durable -it's been everywhere, gate checked constantly, hauled over snow, ice, rocks -around festivals. We got it when our now 6 year old was a few weeks from being 1 for a trip to Colorado. I don't think we ever used our Graco travel system again! When we had #2, I carried him in the Baby Bjorn until he was sitting, and then just used the Maclaren. It is WONDERFUL!
