are there any scooters to rent for handicapped people and how handicap friendly is it?

I know there are regular wheelchairs, I didn't see any electric or motorized versions, there are some hills so someone who is disabled would probably need some help unless they are a very very strong person that can get up at decent Hill on their own

☝ what they said. And be sure to bring an umbrella or wear a hat as theres not much shade

No, John is correct.
