Palm Beach Sailing Club
4600 North Flagler Drive
West Palm Beach FL 33409
Phone 561-881-0809
Fax 561-881-1424

If you prefer a hotel consider;
Hilton, Singer Island Oceanfront Resort,
561 848 3888 phone , 561 848 4299 fax
$95 per night, which is an outstanding bargain for oceanfront this time of year. Very close and nice hotel. Refer to "US Olympic Ranking Regatta" If you have any problems ask for Kristen McKiever in group sales.

Days Inn/Airport North, 561 686 2371, $45 per night. This Days Inn is at the I-95 exit for 45th Street. Safe, clean and cheap.

There are hundreds of other hotels. Singer Island is probably the closest. There are some on US-1 but you have to be careful about which neighborhood you're in. Less expensive hotels will be near the I-95 exits.
