the cruise was not my favorite thing in the world, but it was ok. i didn't like being trapped on the boat for my first trip to AK.i wanted to be off the boat exploring land.
We hit the glacier too, that was very cool. I was amazed how many jewelery stores there were at every stop, be prepared because the ladies hit every one of them.
Get them going against each other and you might get a pretty good deal.
