We have been to Alaska some 14 times and we buy the Toursaver book every time we are going to spend time on land in Alaska. The Alaskan Toursaver book is a great deal if you are spending time, on your own, in Alaska. If you are taking a round trip cruise, then the tour book has only very few coupons that may save you some money.
While pricey, at $99, you usually get your money back when you use the first coupon. The Alaskan Toursaver does have a website that will give you a list of all the coupons. The coupons are for 2 nights for one at various hotels and lodges in Alaska and also 2 for one for various tours and such.
