Wandering from Mandalay Bay to the Four Seasons is like moving from a discothèque to a cathedral. When you witness the expanse of light streaming through the arched windows, one can't help but feel a strange sense which teeters on the edge of spiritual. Guests won't find a casino here, just service. Rooms fill the 35th through 39th floors of Mandalay Bay, accessed by a private express elevator. Quiet luxury abounds, from muted tones, the textured rugs, 330-threadcount cotton sheets and down duvets, to the expansive views, they obviously didn't know when to stop in the amenity department. Room service runs all night, but breakfast is outstanding. Try the Belgian waffles or the cholesterol-free omelets. England invades with high teas everyday at 4, followed by poolside cocktails at 5.
