We would like to do the couple's choice (spa villa) during our Alaska cruise in July. I was first thinking it would be lovely to do it during the morning of our Hubbard Glacier day . . . hot tub and beautiful views, but then I started thinking about the weather . . . ice cold! Does anyone else have experience with the spa villas during really cold weather . . . Alaska, Northern Europe, etc.? If so, please tell me whether this is a good or bad idea to do this. Thank you!
