I took my mother-in-law on a Princess cruise in March 05 and she used a walker and never had a problem. Off the ship she used her cain/walker as needed. She had such a good time we leave again DEC 3rd, 05. My mother has been cruising for yrs and uses a cain to get around. Again no problems. Both use a wheelchair to access and depart the ship. They love the attention.
Enjoy Life & Crusiing
