HOTEL RESERVATIONS

A block of rooms is set aside at the symposium hotel. NOTE: Hotel rooms in the Bay Area are extremely difficult to find. A special single or double rate of $159 (plus tax) has been arranged for those with a U.S. government ID and $199 for all others. This special rate is available from May 6 to May 12. The negotiated government rate is within the “actual” lodging per diem for the area for “Conference Hotel”. Your US government ID will need to be presented at hotel check-in to guarantee this rate. Attendees are responsible for making their own reservations directly with the hotel. Attendees must mention the Aerospace Mechanisms Symposium to obtain the special rate. Requests for reservations must be made by April 10, 2001 to ensure obtaining the symposium rate. After this date, the hotel will honor the special rate on a space-available basis only. “No shows” are billed for the first night’s stay. All cancellations must be made no later than 6:00 PM on the day of arrival to avoid this charge. The hotel address is:
