Batty Over The Hyatt Regency/Austin
The Hyatt Regency is classy enough in any city, but in Austin you have the added thrill of it being right next to the Congress Street Bridge--home to the largest bat colony in America. At dusk, thousands of bats emerge from the bridge struts and fly out over the river. Quite a site!
The hotel boasts the most comfortable hotel bed I've slept in this year. Plus their bar is awesome, they have sushi chefs just off the lobby who, if you challenge them to be creative, will prepare some of the yummiest sushi rolls around, and live music too. 
And did I mention they're in walking distance of the infamous Sixth Street and famous Threadgills? Well they are. Plus I could see the Aussie's outdoor volleyball courts from my window.
