Hi. Hoping someone can help us. My DH and I plan to cruise Alaska next May. I have done some research and narrowed our options down to the following three ships: Carnival Spirit, Holland America Ryndam, or Island Princess. I honestly cannot decide which ship I prefer. Carnival is most familiar for us since we've been on 7 cruises with them. We've also been on a Princess cruise before. Ports are pretty much the same except the Carnival ship is round trip from Vancouver (so somewhat cheaper airfare). We're in our late 30s and enjoy some night life while cruising (disco, piano bar, etc.). No kids, so children's programs are not a concern. If anyone could make suggestions, I'd sure appreciate it. Thanks.
