Nassau with a wheelchair

I will be traveling with a wheelchair-bound person when the Allure stops in Nassau. Is there any place I can take this person very close to the ship? I will be pushing - the chair is not electric. How difficult is it to get around the area where the ship docks? Does anyone know if the area is paved (meaning smooth rather than cobblestone)?

Thank you for any help.

sidewalks along the wharf are concrete and easy to navigate. (sometimes crowded). Bay Street is smooth as well, but only a few ramps for crossing. I have seen many wheelchairs, electric and manual in both areas. The street that the pirates museum is cobblestone. you can take a cab to the zoo. Quite a bit of the walkways are either concrete or macadam.

Thank you.
