I have a membership and I have been going now for about a year. I love it. It is so relaxing and the massages are so great. All of the RMTs I've been to are very professional and know exactly what they're doing. They let you know about areas of tension they found and really work out the knots.
I really think the membership is a great idea because it forces me to go once a month and I've really noticed a decrease in stress. My back always feels so much better and working on my feet as a nurse it's a great help.
If you have benefits that cover massage you can also submit your bill to your insurance company.
If you've been thinking about going in to try it out then I say go for it!
