Really like the whole "Contempo Spa" concept. This is more of a self service spa. There are private rooms for hydration station, sauna, tanning, massage beds.... and more.
I really like their red light therapy sessions too! and their Lumiere treatments.
You can pay a monthly fee for unlimited treatments. And because the Green Valley and Fort Apache ones are owned by the same owner... they'll give you a good deal on the monthly fee.
