I used to do summer/winter camps with 5-8 year olds and with my co-worker we would take 8-16 kids on the bus all the time. it was a great experience for them and a good life lesson. with the younger ones i have done the city bus once and it was not easy with a triple stroller, nobody helped me and i was stuck with it in the middle... luckily it was only a couple stops... a double may be okay if its one of those low rider busses...
