11. Offer packages
Because the concept of a day spa implies a day of pampering similar to what you might enjoy on a spa holiday or a cruise ship, it’s common for spa owners to offer packages of services. Generally speaking, packages should consist of at least one or two complementary services, or in the case of hydrotherapy treatments, one hydro service and up to two “dry” services.
Spa industry insiders recommend offering half-day packages that run about three hours and full-day, five-hour packages that include 30 minutes to an hour for a light lunch.
