Our family is cruising on the Conquest April 10-17. My husband is handicapped and totally dependent on wheelchair accessibility. I did contact the company in Cozumel for the "Catamarian Sail, Snorkel & Beach Party". They e-mailed back stating they can accomodate him totally. If is is not able to get out in the water or on the beach, they said he can stay aboard the Catamarian and enjoy the view. The boat does get pretty close to the beach. You may want to see if you can contact the Fiesta Part Boat owners to see what they recommend. Hope you enjoy your cruise.
