I just got my son ( 3 yrs old, 39 lbs, 39 ") a new Combi SUV just for our Disney Trip next week. We've been using it in our living room and I like it so far. It's very lightweight, reclines and has a hood. The basket is small, but that's ok. My son's feet do not touch the wheels unless he really makes a big effort. It only cost $50 with shipping which is just about $8 more than the cost of renting one for our vacation so it's worth trying it. It might even still fit him next year too, depending upon how much he grows.
I was concerned that it wouldn't be wide enough in the hips, but it's fine. (and he is not a skinny boy)
