The scooters have numbers on them along with the brand name from whom you rented. However, I know from experience that does not work!! In November of last year, I parked the scooter across from the Buzz Lightyear ride to do a few difference attractions in that area. When I returned, my scooter was not to be found. I called the company, they asked me to look for other scooters in the area belonging to the same company and there was only one there! Low and behold, they called that person (from the scooter number and their records) and she had my scooter and was all the way across to the other side of the park already!! It only took her about 20-25 minutes to get back, but would you believe she did not know where to find me and her scooter!!! Apparently, she didn't realize the scooter had numbers or where she left her scooter. That was an hour or two out of our park fun!
