Mostly yes
The drive thru open?
Technical yes. If someone plans to push themselves in a manual wheelchair then no. It's steep inclines throughout. It's just in a Hill area, so the walkways naturally follow the slope.
The paths are wide and fairly level. There are a couple exhibits that have stairs. There would still be lots to see.
Yes. Accept for the bird, alligator, and giraffe exibit.
