The Shore Club is somewhat small, and hidden off of the beaten path, but this can also be a good thing. There is ALWAYS a Hotel worker that is "on guard" @ the back entrance (pool area) to keep the non-guests out. It is a great place to relax. Also it is right next door to the Setai

(which is the most expensive, newest, and most elegant on the Beach. I am not totally sure is the front part of the Setai (all hotel suites) is done yet. It is done in a Japanese theme inside. Lots of teak, stone etc. They just built it this spring. The big Setai (beach side) is many floors 50+ and I think Lenny K has a condo in it. The parking garage is kind of a joke. (engineering drop-out designed it) VERY narrow stalls. For the best 'private' sun bathing, the Shore club, and Setai area are not packed with regulars. (read-- many topless women here) Loews is down a bit closer to Ocean Drive, but also comes more tourists. Stop in @ Mango's at least one night while you are there (ocean drive) Grab a street-side table, have a few cold ones, listen to some great latin based music, and watch the Gallardo's, Murci's, Enzo's, Carrera GT's drive by!
I love SoBe, too bad my wife does not like all of the hustle. She is more into Key West. I was there for 3 weeks in January of this year, and did not want to go home!
I wish you the best of luck. Oh yeah don't forget the dance clubs at night!
