Need some cross country time

Well, I'm in need (and want) to get some good cross country time in.

I was thinking about flying from Oklahoma to Louisiana or maybe some place east of here and doing a long triangle. I was thinking of a 3 to 4 day trip. Gain about 25 to 40 hours, gain some good CC knowledge, work with ATC, and just get away.

Any suggestions?
Feel free to leave a note and some suggestions. Where to stop, places to see, where to eat, etc.
