Before delving into the nitty-gritty, it's a good idea to spend some time exploring the different sorts of destination spas available. The activities offered vary from spa to spa, so it's important to make sure the spas you're selecting from have everything you're looking for.
Outdoorsy types may want to zero in on destination spas that feature horseback riding lessons or kayaking expeditions. People looking for complete pampering may want to select a spa that offers multiple types of massages, body wraps and facials. Someone hoping to shed a few pounds will want to be on the lookout for a spa that highlights an assortment of aerobic activities and consultations with dieticians. If an overload of stress is the major issue, a spa that teaches meditation techniques and provides time for quiet soaks in a whirlpool could be the ticket.
Of course many spas offer a combination of services. Just make sure the ones you want are covered by the spas on your short list.
