The Cheapest Luxury Hotel in Every State

Luxury is defined by excess: a luxury hotel has features that you don't strictly need, making your stay special. But the cost needn't be excessive. South Dakota and Ohio each offer a night in a four-star Hilton DoubleTree for less than $100 ($73 and $86, respectively).

The cheapest five-star hotel in the U.S. is the ARIA Resort & Casino in Nevada ($179/night). The ARIA 'glistens like a futuristic oasis in the heart of the Strip', according to Fodors.

Methodology: We used Hotels.com to search for a one-night stay on the same date for each state at least 10 weeks in advance of the stay. Using the filter feature, we isolated hotels with a five-star rating in each state. When no five-star hotels were found for a state, we searched for four-star hotels.
