I went there for a week last year! I have to say, I wasn't too impressed..too many people stuck very much up their own arse. Its a city fuelled by cocaine and silicon..I don't mean to be harsh but I had a lot of money nicked when I was there and it left a bad impression. Seemed a bit sleazy to me too..
That aside, ahem, it does have a great beach and great bars (there's one latin bar called Mango's on Ocean Drive that goes off every night in the summer - impossibly beautiful people dancing with very little on, on the bar and superb live latin music!)
And there is an outdoor club on the beach called 'Nikki Beach'. A bit pretentious, ferraris and lamgborghinis in the car park (ok I maybe a bit jealous!) but they play great house tunes and get big name DJ's..massage tables, little private tents etc...is definately worth a look. Doesn't compare to Space imo

I didn't make it to Space in Miami, which is meant to be pretty good, but I went to a place on Washington Avenue (just behind Ocean Drive) called the Crobar.
I have never heard music and bass so loud in my life...I wasn't on one, so didn't really get into it and it was very dark with a few suspect characters lurking in the shadows, but it could be a good laugh with a few little friends and people you know (if you know what I mean).
To sum up - not for me but I can see why people love it.
