Are there scooters for seniors to use?

Yes get them at bass pro

I didn't see any but they might have some.

There up front

I didn't see any that were available, but I believe you have to ask to rent one.

Yes in bass Oreo.

I saw people in scooters. . . .

Yes

My wife used one from Bass Pro but when we went to go thru the aquarium the security said we couldn't take it in there. He said the aquarium had there own, we asked for one when getting our tickets and they said the rental was $20. My wife walked and we took it slow.

I did not see any. You can bring your own.
