W New York Rating: 4.0 Pearls
The W New York houses one of the city's most popular spas, Bliss, which originated in New York but has now expanded into franchises all over the world (usually in conjunction with W Hotels). Located on the hotel's fourth floor, this brightly lit spa with cloud-covered walls and a happy blue color scheme has an extensive menu of available treatments. Compared to other luxury hotel spas, the prices are reasonable -- manicures start at $25, massages at $70, and waxes at $15. There is also a Bliss boutique on the first floor of the hotel, and all guests receive complimentary Bliss toiletries.

In-room massages are available for an extra $40 on top of the regular fee.
The Waldorf Astoria Rating: 4.0 Pearls
The 14,000-square-foot Guerlain Spa -- one of two in the U.S., the other being at the posh Regent Bal Harbour hotel in Miami -- opened in September 2008 and offers a wide range of luxurious treatments using the Guerlain brand's signature products. Most spa treatments (including those tailored for men) cost $300 to $500, but the highest of the high-end experiences is the $2,175 Sublime Deluxe transforming day experience, which lasts seven hours and 45 minutes.
