As others have mentioned, it's really hit or miss with the therapists, but I like the concept of paying monthly for my massages, thus forcing me to actually go get one. I used to always have shoulder pain from working on a computer all day and bad sciatic nerve pain from running, and with the regular massages my pain is gone.
I have one MAJOR complaint though - and I truly hope someone from Massage Envy reads this and takes some action. Every time a door opens and closes anywhere near your massage room - the friggin walls feel like they're going to fall down. It's hard to relax when doors are slamming and walls are shaking.
Oh - and parking is a bitch....definitely one of the worst parking lots in Vegas!
