Agreed. Every monorail carries two or three motorized scooters in my experience, usually operated by guests unfamiliar with them. If this is potentially an issue, it's a huge one.
Honestly not sure they have time for that anymore--should've been done 7 years ago. Need a viable back-up plan to transport guests to and from MK for when the inevitable happens and someone goes to the hospital or worse from one of these things and they are shut down for two months.
