If you can, get hold of a Berlitz guide to cruising which has a good section in it about what to look out for. It also has a list of ships with a rating system to determine which are the best etc.. Kind regard.
We have travelled twice with Ocean Village and on both occasions there were many wheelchair passengers. Most seemed very happy with the arrangements. Hope you find the right cruise for you.
We have just returned from a Med cruise on Island Star. We looked at one of the wheelchair friendly cabins for future reference. They were larger than regular cabins and the bathroom was about twice as big with grabrails and a larger shower cubicle.They are on the same deck as the guest relations desk and one on the deck below.We were told that they get booked up quickly so bear that in mind.
