Cruise ships are able to accommodate wheelchair users, oxygen users, the visually impaired, hearing impaired, diabetics, passengers on dialysis, and passengers traveling with service animals. 

The Americans with Disabilities Act has changed cruising forever for handicap passengers. The cruise industry has modified their ships to provide for the needs of handicapped people. The major cruise lines have a number of disabled access cabins. Just about every new ship built now has larger doorways, handgrips in the bathrooms, outfitted shower stalls, transfer benches, lowered closet bars, and refrigerators in staterooms for vacationers who need to store medications like insulin. Some cruise lines even offer special trips especially for the handicapped to meet and greet people with common issues.
