We just got back from our Alaskan Cruise on the Royal Princess. It was an unbelievable trip.
Here is the first half of our trip itinerary:
Day 1 - We got on bored in Seattle.
Day 2 - Our day at sea. We used our $100 credit for a massage at the spa.
Day 3 - First port in Juneau. Explored the city, and went on a Helicopter tour to the Mendenhall Glacier the "Coastal Helicopters"
Day 4- Spent the day walking around Skagway and went on a 2 hours bus tour to the Alaskan/Canadian border through "Southeast Tours".

All excursions were booked through Viator.
