Never mind saving money because you are only getting half the value of what you're paying for anyway. The real essence of a full spa experience is when the 40-minute satisfaction kicks in. This is according to most spa aficionados in the US and Asia. They can tell that a good massage is essential when they feel relaxed when the 40th minute of the session kicks in.
This is why Soneva Spa has Couples Massage packages that run for good 2 hours per customer.
