Another issue on Mariner is whether to go for a tub and shower cabin, or a shower only. The ceiling above the bathtubs is only about 6' and a little bit above the bottom of the tubs on Mariner, and the bottoms themselves are higher than the bathroom floor. Also the tubs are deeper than standard American tubs, making getting out on to a wet floor a distinct challenge; great care is essential. On a long South American circumnavigation some years ago, I learned to 'shower while crouching', (I'm 6'2") so we always get a shower-only suite on Mariner. Shower-only suites used to be available in Category F and above only, but somewhere I read that some G and H suites will be converted this year. I think bath ‘style’ is the key consideration in selecting your cabin on Mariner.
