Colleen, we were on the Mariner in June 2001. While it was not a problem for us at that time I can well imagine that particular tub design would be a problem for me when the arthritis in my knee gets worse. I remember it as quite a high step up. I've used a walk in shower at home for years but have used tub shower combinations at many places while traveling and the one on the Mariner was higher than any other I remember. Factor in that you're on a moving ship and it can get scary.
