I did this when it was $30 and independent, my opinion only but at $100 now- to me it wouldn't be worth the cost. There are several other options to consider- if you rent a car, there are some kennels in Carcross. Also if going one way- definately add time for interior touring. The bargain of bargains is a cart ride at the Sled Dog Museum in Wasilla for $5. Seavey's out of Seward is superior to the Skagway operation.
