And those end-of-summer deals just keep rolling in. Set in Texas Hill Country just outside of Austin, Barton Creek Resort & Spa is offering up a sliding scale of resort credit to spend any way you like. Stay three nights before September 7, and you'll get $100 in resort credit. Stay four nights, and it goes up to $200 in credit. Book five nights or more, and you'll get $300 to spend on amenities during your stay.

Along with a quartet of top-rated golf courses, Barton Creek offers four restaurants, a spa, indoor and outdoor pools (an enormous outdoor pool resembles a small lake), themed camps for kids, mini golf, an arcade, and a nature trail. Rates start at $225 per night.
