I was in a quandry as to how many bathing suits to pack, since you are in and out of the springs fairly often. They do have dryers, but charge $2!! This could get expensive if you don't like putting on wet clothes and heading out into the winter air. Gretchen only packed one suit, while I took more. There is a clothes line in the shower, so you can hang dry your suits.
Unique Suggestions: I don't like bathing suits, but they don't let you go naked, so I got a four pack of patterned briefs (without the fly) which looks pretty much like a swim suit.
Fun Alternatives: Momma always told me to get out of those wet things or you'll catch you death. So why do we wear things just to get wet? I don't know. Wear whatever is comfortable for you.
The lure of gold brought a rush of prospectors to Alaska, and I have met some who still seek gold, but this is just nuts! For $20 you can pan for gold in a little shack, and they promise that you will get some dust. It ain't gonna be twenty bucks worth, and searching for gold inside a building ain't the way it was done.
Unique Suggestions: You are in an isolated resort, so chances are they are gonna get some of your money, choose some other activity that is more fun, or more authentic.
Fun Alternatives: If you want to spend your money on a skill that you will never ever use again, take mushing lessons. More expensive than a ride, at least you had a real Alaska experience. People do keep teams of dogs and use them for transportation.
