All is set with the other cabins F1 and up. Bathtub and Shower.

I was surprised too and we had to advise everyone booked in the PH that there would be no bathtub. Everyone booked was fine with that. There is no doubt the shower is the most popular choice that has been proven on the Mariner. BUT there are bath people (I am one of those) and if I was upgraded to a PH without a tub I would decline the upgrade.

It just complicates things so much. The Mariner is always an issue we all forget about the choice of the Bathtub or Shower option. Hate to admit how many times I have to call back a client - bathtub or shower? I often get my cabin at the last minute and on the Mariner I am always worried it will be a shower. Since the showers are the most popular the cabins left usually have bathtubs so I am usually fine. Though I do remember getting on my hands and knees to Linda begging her to trade with me -she had a bathtub I had a shower. She willing did so she does not like bathtubs.

I had imagined that problem would not be present on the Explorer and it would be like the Navigator and Voyager - both shower and bathtub in every cabin.

Only thing I can imagine is they have designed a luxurious PH bathroom and the choice was give up this "design" for a bathtub or do a shower only.
