Alaskan Cruise?

So Kyle's little sister is getting married this summer. First she was thinking of getting married in Hawaii. Then she said St. Thomas. Okay, I would love a free vacation to the Caribbean, not that I would turn down a free vacation ever. The reason for St. Thomas was that her fiance's dad has a condo down there and they were trying to rent rooms in the condo for everyone. It was something like $300 a night. Turns out there weren't enough room for everyone. Bummer. So now we have to go on an Alaskan Cruise. The Caribbean or Alaska? There are tons of places I want to go. None of which are Alaska or anywhere near Alaska for that matter. Kyle is incredibly disappointed. Is it going to be cold in Alaska even if it is in July? How does that work? Would we need coats on a summer cruise? I'm not a cold weather kinda gal. This doesn't sound particularly fun. On the bright side, don't you think I would get to see a lot of wildlife? Apparently, whales feed in the waters off Alaska in the summer months.
