Royal Caribbean's Navigator of the Seas

Our ship, and room, have proven very accessible, from the stateroom to the minigolf course, the lift on the pool and hot tub and the seating in the movie room, to the staff's constant care and attention. In brief- highly recommended for the disabled traveller. RC offers some accessible tours, but we are opting for DIY, using local taxis and some maps.
First stop, Messina, Sicily!
