This was my first stay at a JW Marriott property, and I didn't regret it! If you find yourself in Buckhead, JW is a nice choice given the price point and value. For a little under $200 a night, you have a top notch property with excellent service.
You don't have to valet park, save yourself some bucks. There is a parking garage next to the hotel that charges $22 a night. There is also a Starbucks in the lobby, so that's always a plus.
