What is in your opinion the most absolute luxurious hotel?

I stayed at Caesar’s Palace in Vegas for the first time, using credit card points. It was a disappointment—the room was outdated; I got scammed at the Sports Betting kiosks, and the place felt chaotic.

After seeing other properties like the Bellagio and Wynn, I’m concerned about being duped again. Money isn’t a concern; I’d rather save for a top-tier stay. I’m looking for a true luxury experience on the Strip, similar to the Ritz-Carlton. Any recommendations for a five-star hotel in Vegas?
