I read a bunch of reviews about the hotel being snobby and stuck up before I stayed at the W this past weekend. I almost even changed hotels, but I'm so glad I didn't. I've stayed at W's in New York, Atlanta, San Diego, but this one is by far my favorite. The pool on the 16th floor overlooking Dallas is incredible. I was at the pool drinking some of their wonderful mojitos about to smoke my cigar that I brought with me, but I didn't have a lighter or cigar cutter. I called Whenever/Whatever and within 30mins they had someone bring both the lighter and cutter up to me while I was at the pool. Also, the living room (bar) down stairs was also wonderful. I made reservations to go to the Ghostbar online, but didn't end up making it up there. There was a line at the elevator just to get up to the bar. Overall, everything was wonderful and I highly recommend this hotel.
Pros: Pool, drinks, ambience, location, view... pretty much everything
Cons: you can only valet park b/c parking is ridiculous down there, but it was only $24 so that's not even bad
