re: 3 day weekend in South/Miami Beach?

It depends on what you’re looking for. South Beach has more restaurants and things to do but the hotels there are expensive. You’re looking at at least $500/night for a 600-700 sq ft room at any of the big resort hotels. The boutique hotels are cheaper, but the rooms are way smaller and don’t have many amenities. It all depends on your budget and what you’re willing to spend.

The problem with Miami is that any nice resort that’s worth a shite is always overpriced due to the sheer volume of tourists that flock there. That goes for pretty much every single area of Miami Beach.
