During the last two days of our cruise, we spent the time scenic cruising. Hands down, the greatest thing a Princess Alaskan Cruise offers is access to Glacier Bay National Park. Only two cruise ships are permitted per day, along with only twenty-five other boats. If you have the time, I absolutely recommend visiting the actual park. For us, the days cruising were enough, even if they were just a taste. We spent an entire day cruising there, and then spent the next day cruising College Fjord. College Fjord is home to five glaciers that terminate in the water, and is a great experience as well.
