IMHO = In My Humble Opinion:
For class and great ass, any of the following three might do for you:
Hotel del Rey (HDR): Excellent quality women can be found, and if a blind guy (me) can find a hot-bodied spinnerita with mad sexual skills, it shouldn't be too tough for you.
Rooms are reported to be Motel 6 quality with well broken-in beds.
Hotel M. Toney, toney, toney. Expensive private club atmosphere. If there are girls on site, they will be absolutely top-shelf and priced accordingly. Recent trip reports which included Hotel M state that girls were demanding, and getting up to $300.00/hour.
Sportsmen's Lodge/SL: The bar can have 36 different women...or three. It depends on so many factors that a Ph.D. statistician might have trouble following the ebb and flow of the chica tide that rolls through SL. While lesser in numbers than what you'll find at the del Rey, quality can often be equivalent and prices $10.00 - $50.00/hour lower than for a similar del Rey debutante. Downside: Bar closes at midnight. Upside: Smaller, boutique hotel; the new section is on par with Hilton or Hyatt in the U.S. Girls are more "tranquilas," less subject to clock-watching etc. A nice experience, which is why I try to stay there every trip.
Hope this helps.
