based on staying at south beach last year, a small room in good area(but not on the beach) can easily run $300. for the $300 pricetag, dont expect muchMay I ask why? The Art Deco hotels of that area seem to get decent reviews on hotel .com
maybe thats what there looking for. you should just crash on the beach..think scarface chainsaw scene for a 100 dollars a night.. the nice south beach is what you see on TV all the time which is basically just ocean drive ... the rest of it, is crack, prostitution gangs and crime .. be carefull!!!
