I admit I am not handicap, and did not specifically notice those accomdations, but the parking area was spacious and when we went we parked in the front row without issue. There was and elevator to get to the second level, and the first level has many ramps. I don't remember an area that was only accessible by stairs. It's really a great place to visit. Similar to Port Discovery (Baltimore) but much cheaper!
I didn't notice an issue either, it's a huge open space.
