This may seem a stupid question, but I'm a newbie to all this. How do small children travel on the DME buses? We are going on a Disney cruise in a few weeks, and we have reserved transportation from MCO to a WDW hotel, then to the port the next morning, and back after the cruise. We have never taken our kids (ages 7 and 3) on any sort of bus, so I don't know if they need car seats, or if the bus has them, or if we just let them sit in a seat like an adult. This has also got me wondering about getting to the airport at home. Has anyone put small kids in regular seats in an airport shuttle?
