If find yourself traveling to Korat and need to stay in a decent hotel near alot of the action in town, the Choayopaya Inn would be a good choice. The rooms are nice, wood floors, good bed, shower, cable, refrig.
Downstairs, outside in the parking lot and pation in front of the hotel is where the freelancers stay to get picked up at night. This only happens after 2am.
Short time is apprx. 700bht, short time room, (if you are not staying here already) is 420bht. Long time 1,000 to 1,500bht.
