May I make a suggestion? There is a website called cruisedeckplans.com. People submit cabin pictures to it. It is a pay site for most members, but accessible cabins can be viewed without a membership. Pull up the website, choose your cruise line, then your ship, and scroll down the cabin categories on the left. Those with accessible cabins will have ‘handicap’ to click on, and it will list the cabins, and if there are any with pictures there will be a very small camera icon you can click on.
some cruise lines have ships by ‘class’, such as the vista class of HAL, which includes four ships. If you are looking at a ship in that class, but there is no picture of the type cabin you want, choose another ship in that class, as cabin layout will be the same.
There is another board here called Disabled Cruising that talks a lot about cabins, and this thread may be moved there. EM
