Rio de Janeiro will host the UN Conference on Sustainable Development http://www.uncsd2012.org/rio20/ with a program that begins on the 13th and ends on the 22nd of June. According to O Globo this morning there are already 150 confirmed heads of State coming, 190 official national delegations and 50,000 already registered visitors (diplomats, journalists, business people, politicians). An estimated 10,000 people are expected to camp. All this presents one tiny issue: Rio de Janeiro has only 27,000 hotel rooms today! The Copacabana Palace and the Sheraton Leblon have been booked in their entirety by official Head of State groups and almost all other hotels anywhere around are full. In Centro the occupancy is so far only about 80% (nobody important really wants to stay there) and all teh high-end properties are totally booked. So, it seems to be an excellent time not to come to Rio de Janeiro! Too bad June is a nice cool month, my favorite month of the year under normal circumstances. I plan to leave town myself. Anyway, it is safe to say there will not be very many seats available during that time.
