I am actually Platinum with Marriott and is eligible for the B1G1 offer. however, that is only for weekend. 1 weekend 1 free. so, only 2 out of the 6 nights. & yes, coupon does say can give to friends. I believe the calculation for Austin-South-Airport Marriott is about $50 per night before tax. However, the rest of the week will be more than $100. budget? I was hoping to keep in the $50 range before tax per night.
