The NN2012 room rate is now reduced to $129/night (plus tax) and it includes complimentary internet. This rate is valid during the meeting and 3 days before and/or after the meeting. It is also retroactive for all NN2012 reservations made before May 7. Please make your reservation as soon as possible before the cut-off date of May 7.
