"Since the introduction of the Princess Access program, Princess Cruises has been very consistent in raising the bar higher for accessible travel. In fact, the line is highly regarded for its impressive accommodation of cruise passengers who are mobility-restricted.
The line features more than 350 wheelchair-accessible staterooms with much wider entry doors, roll-in showers, hand-held showerheads, handrails, closet railings and lowered sinks.
In addition, Princess also boasts spacious lifts ranging from 91cm-106cm (36-42 inch) doorways. There is also a fleetwide wheelchair seating in the ship’s public areas."
