I say if you have the miles, use 'em. $850 is $850. That's an entire year's season ski pass at some ski resorts! 32-40k miles is a couple of AA citibank sign up promos and a 1-2 point hit to your credit report at worst.

If you do not have enough miles, some friend or family member can book it for you with theirs and you bring them an Ididerod sled trophy for helping you out
