Yes. The cafeteria is at the visitors center, and you can pull up right next to the visitors center to let out a person with a walker/wheelchair/etc. There is a bit of a walk on a paved downhill path (no steps) from the regular parking lot to the visitors center, so when I bring my mom with her walker I always drop her off right at the visitors center. There is a bus that will take you from the visitors center to the mansion/museum. At the mansion/museum you can board a tram, which will take you for a nice long tour around the gardens. Hope this Helps!
Yes, they have a train to museum and store with cafeteria.
