I have been a Marriott Rewards member since 1997 and have always opted for points verses miles. However, I know my points add up alot faster than mileage (ff with AA and UA) so I almost always end up having to pay for flights when on vacation. What do others think about points verses mileage? I know we now have the UA Premier option so maybe this is a mute question since you can transfer without penalty, but would it be cheaper to pay for Marriott hotels per stay verses paying for airline tickets? Sometimes the airline tickets can be pretty steep.
