From the Sonesta New Orleans site:
In addition, for groups traveling in Jan, Feb or March 2006, who insist on cancelling and who we are unable to rebook at another Sonesta, the policy will be to allow them to cancel without penalty. It is premature for Sonesta to have a firm policy regarding groups booked beyond March 31, 2006. We are presently working hard to make sure our hotels are in condition to assure guests an appropriate Sonesta experience and, while we are aware that the City may not be fully restored to its former luster by the end of March, we will be monitoring the pace of restoration closely over the next few weeks. A policy regarding post-March 31 group bookings will be made within that time frame and, in the meantime, will be determined on a case by case basis in consultation with our hotels.
