Does the entrance have a ramp, for a person in a wheelchair?

Hi, you are able to enter to the outside and inside area on a wheelchair, no steps, however outside area the ground is basically composed of little rocks so, wheels would not be able to roll smooth. Inside restaurant is much better for wheelchair and you still will enjoy the bands. 😉

There is no ramp from the dock to the boat.

Yes

Yes, the main entrance is at ground level, and the deck area is very similar.

Yes you are.
