Carribean Cruises with disabled access

Hello, I wonder if anyone could help. I would like to send my parents on a Carribean cruise as a big thank you present. It has been their dream holiday for I dont know how many years. Therefore, for this special occasion I want to get it right. My mum is registered disabled and finds it difficult to climb stairs. She is also unable to acces regular swimming pools but loves getting in the water. Can anyone give me an idea of Cruise liners/companies that cater for customers with these requirements? My budget is approx £2000pp.

Any help would be greatly appreciated

Many thanks

Since you are just beginning this process, my best advice is to read this section of the boards for research and then check with the special needs department of the cruise lines you are interested in. Most of the newer ships have lifts at some pools.

Good luck.
