What is the Best Luxury Hotels in the United States?

I think the best is Montage Palmetto Bluff

Bluffton, Coastal South Carolina, South Carolina

This sprawling estate in Carolina Lowcountry provides a one-of-a-kind experience that uniquely blends southern history and almost otherworldly natural beauty: rivers, misty marshes, old oaks draped with wispy Spanish moss, and salty breezes. The main hotel building looks like a classic southern mansion, and the 50 Cottages and Cottage Suites are simultaneously homey and utterly luxurious, with working fireplaces, screen porches, and gorgeous bathrooms. The multi-bedroom Village Homes are also luxurious, but lack some of the nuances of the cottages. Guests can enjoy a range of recreational facilities, including golf, bicycling, tennis, croquet, kayaking, and swimming (in the two pools), and the luxury spa is highly acclaimed. It's not an overstatement to say that the Montage Palmetto Bluff is one of the most special properties in the entire country.
