A common scam in the town is that the hotel managers may give incorrect information about bus schedules to make travelers stay at their hotels longer. Double-check with the bus companies yourself.
Having said that, though, Kahta is a fairly safe area. You can just go out, take a walk to Atatürk Dam, have a very nice dinner in fish restaurants just next to the dam, and enjoy the cool air in the night.
Some travellers report being misled by the local tourist/information office, so if you're concerned about this possibility, try to cross-check information or advice they give you.
