With the change of the United Nations Rio+20 dates, the local Rio+20 organizing team has still centrally booked the majority of the hotel rooms throughout the city of Rio de Janeiro.
We are currently still awaiting release of rooms to us for the ISEE 2012. Other pre-events are in the same situation.
We are monitoring the situation closely and as soon as the rooms are released, we will keep you posted. Thank you for your patience, and we hope see you in June!
