As an Alaskaner, let me personally congratulate you on picking the shittiest possible way to see the state. I hope you didn't pay for it yourself.
Have fun waddling around with the rest of your morbidly obese shipmates and seeing the most disneyfied towns in the whole state.
And when you're in Ketchikan, Don't go to the arctic bar; that's the fisherman's bar; you will be beat up.
Don't go to the totem bar 'neither, that's the Native's bar; You will be stabbed.
