This August? Wow, I'm amazed that you can still book, I hear the Alaskan cruises fill up fast!
H and I have one book for next year already. We are going in May for our anniversary and also because in our company it is hard to get vacation in the summer (especially for me since I have low senority) so it will still be pretty chilly. I'm not sure I will like it but it is right up H's ally and since we have gone tropical for me the last 2 years, I figure its time for his vaca of choice.
