For us, we stayed at the Palazzo years back. Paid casino rate which was still pretty high. Room was great but just really did not get an offer that amounted to making if appealing.
Wynn, stayed on a casino rate and really liked the special touches that seems only Wynn can do. But, once again no a big enough Whale (minnow perhaps) to get many offers that totally wanted our return. Palyed the golf course when it was Desert Inn but not once Wynn took the rate to $500 per 18.
Full comp still available at Cosmo and Caesar properties and a few downtown. We really enjoy everything about Cosmo but must admit have not been back to Vegas since parking fees have started. May look at a trip this summer/fall, hopefully.
