 Guests reside and participate in the program at a destination spa instead of just visiting for a treatment or pure vacation.Some destination spas are in exotic locations or in spa towns.Destination spas have been in use for a considerable time, and some are no longer used but preserved as elements of earlier history; for example, Gilroy Yamato Hot Springs in California is such a historically used spa whose peak patronage occurred in the late 19th and early 20th century.
