We have booked most of our shore excursions in Alaska through our cruise line, Princess. But, recently I have been looking around the internet and it seems that many say that you can avoid the expensive tour to the Mendenhall Glacier (45.00 pp) and just catch the bus that is near the piers (Mendenhall Glacier Express- blue buses). Most review say the service is good and frequent, the cost is cheap (about 6.00 round trip) and you can stay at the Glacier as long as you want and catch the bus back to the pier. Has anyone travelled to Mendenhall Glacier via these buses rather than taking the tour offered by the cruise line? Was it good service and could you stay as long as you wanted at the Glacier. Your thoughts please!
