I'm Going to Miami!

I'm looking for Miami Beach hotel accomodations. The prices are pretty steep even on the online discounted sites like Expedia. The ones in decent South Beach locations are going for at least $200/night. Maybe I was too irrational when I booked my plane ticket the other day. But I couldn't resist from the temptation of getting my feet back into the warm sand; I can hear the sound of the waves calling me right now!
