We went to Vegas for my brother's wedding last week. We were headed back to Excalibur from Mandalay Bay when without warning our team slams to a stop mid-track. My mom was on a scooter and my 7 month old son was in a stroller, both of which two wheeled and would have gone completely over if my husband and I hadn't been standing next to them to stop them. It did however knock my 2 1/2 year old down to the ground. A little communication would have been great so everyone knew this was actually a roller coaster, not a peaceful tram ride between hotels.
