I've only played AL, AR, GA, FL, MS & TX, so take it FWIW. If I could had to choose only two places to ever play again, I'd go with the RTJ Trail in Alabama and the courses of the greater San Antonio area. Either of those places would make for a great week of golf.
Of the RTJ courses, I prefer those in the southern half of the state. You can stay in Montgomery, AL and have five of the RTJ facilities within a 60-75 minute drive. Two of the best facilities, Capitol Hill and Grand National, are 10 mins and 45 mins respectively.
Having lived in San Antonio for a couple of years, it's hard to beat the combination of great weather and selection of courses under $75 (twilight rates at some). You could play every day for two weeks and not play the same course twice. Some of my favorites in the SA area include The Quarry, The Golf Club of Texas, The Bandit and Pecan Valley.
