Cruising Alaska, one of the most “outdoorsy” state in the U.S., is more popular than ever before, but you can still find a great deal if you’re flexible, especially in the summer. A 7-day cruise aboard the Grand Princess of Princess Cruises makes stops in Glacier Bay, Skagway and Juneau, among others. The reasons to visit the Last Frontier are endless – unique wildlife everywhere, migrating salmon, mighty mountains, and national parks.
