Robert, The last time I was in Vegas, which was the year before last, I simply went up to the front desk & asked for canceled keys. I had no trouble getting keys in most of the hotels, except for the Excalibur. There I went to the bellman & asked. When he produced the keys I tipped him a quarter or fifty cents. He wasn't too thrilled, but I think he misunderstood me when I said 25 or 50 without a specific denomination. <g>
