I have really never had an issue with scheduling a massage at this location. But of course while living in Phoenix I have only been to one other location (Happy Valley/Norterra).
They have always been rather busy and often appear unorganized at the front reception area. Well there was that one time I needed to break a large bill to provide a gratuity and they didn't have change. Luckily Jimmy John's next door did it for me without me having to purchase a sandwich.
There have been times I have been able to schedule a massage for 15 minutes from the time I was calling in while I was next door at Total Wine shopping. I have yet to find a dedicated massage therapist here, mostly due to my random scheduling habit. But I for the most part have not had a memorably poor experience here.
Which reminds me I need to schedule a massage soon. I have 4 1hr credits. I find an hour a bit short but an hour and a half to be just perfect. Now 2 hours can be a bit long for both myself and the therapist, but I have scheduled them on occasion.
I am a member and I have enjoyed the convenience of being able to use my massage credits as I travel. It has saved my back more than once.
