Looking to stay at the Esalen Institute in Big Sur? Now’s the time because bookings are down 25% at the “human potential” center, which draws 10,000 people a year to its hot tubs, massages and seminars. Even Fourth of July weekend, normally booked months ahead, has room. Esalen reopened in May after being shut down since Feb. 3 by El Nin~o storms, which wrecked its bathhouse and damaged some quarters. Temporary hot tubs, in horse troughs, are to be replaced later this month with three large redwood tubs. Information: (408) 667-3000.
