I wish the Sapphire had a sanctuary. Perhaps I would try it if I wasn't going during the colder, rainier season.
I think I read somewhere that they plan to put that in as well as MUTS, but not until after my trip. (?) Hopefully someone will clarify for me.
But Sapphire is not the only Princess ship to sail Alaska and I'm not sure what those other ships have.
It wouldn't bother me to sit in peace and quiet with a good book, just give me an extra blanket and a hot chocolate with Bailey's Irish Creme!
