Most of the modern ships have wheel-chair facilities on board and special adaptations to go ashore that make it very easy. They are totally used to people with disabilities and their needs and those of the carers so go with the better lines, P&O, Princess, Holland and America, Royal Caribbean, Celebrity, Cunard, N.C.L. and Azamara and you will be made to feel at home (many of these sail from Southampton). Ask for one of the cabins for disabled passengers and be sure to take your Blue Disabled Person Card with you as these are accepted all over Europe and will give you better and often free access to many sites. Even in America where it is not recognised you can show it prior to parking a hire car and be treated advantageously. America provides better facilities for disabled people that probably anywhere else in the world. If you are going to fly airlines will carry you wheelchair free and give you ( often) better access seating and at the airport provide assisted passage to and from your departure and arrival gateway. Things are changing for the better but they are already pretty good so go and enjoy it…..Ida.
Try RCI we found them very good when we traveled with a disabled relative you get escorted onto the ship and the excursion staff helpful in booking any suitable trips if you require it help is available on and off the ship at the ports not all ports have good access for wheel chairs ,there are areas reserved the theaters for disabled passengers,there are ramps into lots of bars and the casino some of the pool areas have a hoist so the pool is also accessible,they seem to accommodate every type of wheel chair and if you book early or late season there will be less kids on board.make sure you get the disabled parking sorted as this is just outside the departure ares at Southhampton go and enjoy.
I agree wholeheartedly with previous review and would like to add one other tip. Choose your cruise itinerary carefully. At some ports passengers are tendered ashore. This means transferring to the lifeboat-type small boats and is difficult for wheelchair users. Sometimes ships cannot, for safety reasons, give this service therefore you would be limited in your ability to get ashore. Check the brochure itinerary carefully and ask your travel agent to recommend cruises where no tendering is involved.
My wife is confined to a wheelchair and we went on the p & o Oceana in April 07 and had a great time have booked again in September 08,My advice is go down to Southampton the day before we stop at a premier inn in Southampton night before it take the stress of getting on the day as you are about 20 minutes from the port.
Good luck and injoy your cruise.
