It's extremely simple to book direct with Alaska venders and I would NEVER use any booking agents- middle men- as the above poster did. Glacier dog sledding is over so the only dog sledding option is a cart ride out of Skagway. Determine if this is something you want to do- there is no comparism with this and snow. I have flown with Southeast Aviation, Carlin Air and Island Wings to Misty Fjords. Superior operators compared to ship contracted. You may be able to get a cheap used Toursaver book since the season is almost over- look on ebay and post a request on various boards- BUT determine if "coupon space" is still available.
