is it wheelchair accessible / able for riders to sit in their wheelchairs, in the buckets.

There's room in the cars. There maybe issues accessing the platform for entry of the car. There's quite a few steps to climb upon entry and exiting on the opposite side.

Yes

Yes/No

I'm not sure if they have wheelchair accessible Buckets. The buckets have 2 stationary benches across from each other. They may have some that are for wheelchairs I'm just not sure
