I have both a little folding potty and a folding potty seat from One Step Ahead. The potty is good to have in the car for emergencies, and trips to the park etc. We used the potty seat more for everyday trips to the mall, Disney etc. The potty is great but DD was probably 5 the last time she used it---it is pretty small. The good thing is it's set up with a plastic bag with a pad inside, so you just "go" into the bag, on the pad and then throw the whole thing away. Great for little kids, but I don't think it would work for your older ones.
