Heading for a long trip between going to Disneyland, Universal studios and L.A. from 2/6-2/15 I'm worried my turning 5 years old son during the trip (Small for his size) is going to be way wiped out without having one available. We don't use strollers for anything else but this is such a busier trip than our usual day to the zoo or what not. Do you use strollers for your newly 5 year old child? Or best to skip it??
