f-mattox warning is very good advice. you'll need an HC accessible cabin if you're confined to the wheelchair. They have roll in showers and turning radius for your chair in the stateroom and bathroom. Also wider doorways for both. Your T/A should be able to see not only if they have some available but also get with the Special needs Dept to see if any are presently booked to clients without such needs. They do book them on request to those without need but require they be advised if clients with needs book they'll have to give the cabins up for another equal or higher category cabin. They know who has what because of the forms they require for special needs passengers. Press your agent for some assistance in this. If they seem to not be willing or able, get another agent who is. You can, believe it or not transfer your booking to another agent or even agency at your request.
