Hi Shana, Hawaii is very handicapped friendly
the curbs are easy to manage and there are lots of transportation that is handicapped accessible
We were together as a family and rented a car so that was easy for me.
Most of the the tours involved walking so I did'nt go!
What ever ship you take will be able to give you that info.
You will love Hawaii and the all the islands.
Hope that was of help HETTY
