I'm in Miami Beach right now. Miami is a very large and diverse area. Can you be more specific about which areas you're interested in? We're in a very nice 3.5 start boutique hotel in Bal Harbour for $200ish a night. I've always had luck here scoring 4-5 star hotels on Priceline in the $100-$200 range. You need to do some legwork to gain an edge here
