I believe it. I stay at Harrah's properties all the time. I was at the Rio last week.
I would gladly stay at Paris, PH, Bally's too. I have even stayed at Bill's now and then if I just need a night or two.
I usually get comped because of my play at Harrah's AC. It's a good system and the offers are frequent for all the locations.
Again, the "classy" places are becoming less desirable. I just have to convince my wife.
