Just be nice.
I wasn't supposed to be in Las Vegas, but here I am with no hotel and every place is booked or as expensive as a mortgage payment.
That's when I called Super 8. They were very friendly and told me every place was booked up. But they had rooms. Here's where the being nice thing comes in. After waiting on hold the front desk clerk said he could save me a room and since I was so patient he was going to do me a favor.
The outcome was a great room at an unbelievable price. The bed is really comfy, the place is spotless and really great graphics on the walls. For under 50.oo Super 8 has made me one satisfied customer !
