Most Las Vegas places give lower rates on Sunday through Thursday. We found a great online deal for 3 nights, Sunday-Wednesday for under $30 a night. Large clean room with a king bed and sofa sleeper. There is a safe, a tiny refrigerator was included, and coffee maker, but no microwave. There were double sinks in the bathroom, and everything was spotless. It's away from the strip area,with less surrounding noise. The hotel staff were welcoming and efficient. The complex has bowling, a pool +spa, good selection of restaurants, and movie theaters, as well as gaming.
If you don't mind being away from the strip, give this place a try.
