We started the day with a tour on the Riverboat Discovery. I had some doubts when I booked this, since it seemed to be included in all land tours passing through Fairbanks. However, it was a good time and very informative. We also ate the family style lunch in their facility after the tour, which was very good too. Then we drove to Denali NP and began with the Visitors Center, which we were unable to visit while on the Princess tour.
