I think you are asking if anyone has used DVC points to sail with Holland America Line in Alaska - I did the 7 day Seward to Vancouver last June - what a GREAT trip....my only reccomendation is that one take books or DVDs with a small player. The ship basically shuts down at midnight. I was the youngest person on the cruise (I am in my early 40's). The scenery, excursions, and all the trip were so beautiful! The captain pushed hard to make it to the Hubbard Glacier since he had gotten word that it was calving that day - we saw over a dozen calved pieces and were amazed to find the crew standing right next to us taking pictures as well. Seems this glacier doesn't calf that often!! I recommend the 7 day that goes either north or south - the loop from Vancouve doesn't see as many ports. For excursions - we booked the "best of" at each stop (except Ketichican - that was the off road jeep trip) and saw so many whales, sea lions, eagles and other sights.
Feel free to PM me for further suggestions and information.
