yeah I used to spend about 4 months a year there since 2000 when my daddy lived in south beach.
I would party/ go clubbing like 5 nights a week as opposed to 1 or 2 in manhattan. many clubs are right there in south beach a few blocks away or theres space across the bridge in downtown.
between all that drinking, sitting on the beach every afternoon baking, etc & the brainless people, it really started to wear on me.
I will say this, its a lot easier to have casual sex in miami than it is in manhattan. the kids in sobe seem to exist to hookup!
and there are tons of models walking around south beach, buit not always the higher level girls.
as far as bathing suits, i should also mention that the better hotels like the Loews and the Delano also have shops that sell designer or at least trendy/pretty swimwear. if you want more miami info or club ideas write me, its probably my second home still.
