Travelocity has a coupon offering $50 off a two-night ‘Travelocity GoodBuy’ hotel stay booked by November 30th (requires paying with Mastercard). Promo code is HOTEL50.
If the discount code doesn’t work for you it’s likely that you have a Travelocity affiliate cookie on your computer (eg you clicked on a Travelocity link somewhere, such as from a cashback mall). Travelocity won’t let you use the coupon and pay someone a commission on the booking at the same time, so you need to delete these cookies for this to work.
There’s a current Flyertalk thread on hotel stays you can get for free via this promo, mostly centered on Las Vegas properties.
As one Flyertalk member observed, “just because the icon “Use MasterCard® and SAVE $50!” is not listed with a GoodBuy hotel… the promo most likely works (NOT all but MOST I’ve found in my extensive searches).”
