So, it turns out I have a trip to Rio with a friend scheduled, arriving on March 1st. Neither of us got around to arranging accommodation, and now it's scarce. My friend has business contacts in the city who are working on finding some place for us, but even they are pretty pessimistic. Anyone have any clever suggestions for getting someplace to stay in Rio during Carnival? Don't need any particular brand or chain, as long as it's not a brothel (most of the places that show up on searches are prominently labelled Adult Only).
