Can I rent an electric scooter like the one I got in Orlando?

Yes

Yes you can

I think they do have those as well as wheelchairs

They have electric wheel chairs are available to rent

You can try but I am not sure how it goes

I saw kids riding scooters. Not sure what you had in Orlando. I would imagine they have the same thing in Hollywood

I think just for seniors

Not sure what you had in Orlando but you can rent them
