My husband cannot walk long distances - ate there any of the sit down drive your self carts available?

They have elevators but no steering carts. And several sit down testing and interactive exhibits while sitting.

No, no riding carts. There are several places where you can sit and take a load off though. Ifc he can make it from the parking lot to the exhibits, he should be fine.

I do not recall seeing any. Give them a call and ask.
