At Kona you use the tenders to go to shore. We had a disabled person in our group who was unable to go to shore as they can only carry a person on and off the tender. They did not mind not to be able to go, the only problem was the ship does not tell you that before hand, and the crew at the disembarkation station was rude, they saw her waiting there for a while and then very tersely said she could only go if someone was going to carry her as the crew would not, and that they really did not have room for the scooter. On past cruises with Royal Caribbean, they could handle the person when we disembarked on the tenders. Otherwise, Kona was a great port, with lots to see, shops, restaurants, activities and beaches. Suggestion, if you want to go to the Kona Brewery, go early, later in the day there can be up to a 2 hour wait for a table.
