I've stayed here many times over the years and the Four Seasons has always been my first choice, but the number of dogs on the property has seriously gotten out of control. On my recent stay I could almost literally not get on the elevator without someone's little yapper trying to bite my ankles, and I almost never walked down the main hall to the lobby without one or more dogs being walked in the hallway. It takes the ambience from elegant to trailer park in a hurry. Fortunately there are no shortage of 5-star hotels in Las Vegas to choose from.
