Like many people, I purchased the excellent deal in December 2011 for 20 classes. I have mixed feelings about the place.
Pros-They do an awesome job of heating the room for hot yoga. Lots of places claim to offer hot yoga, but then the room maxes out around 80-85 degrees. For those of us yogi's who love us some steamy yoga that's disappointing. Arrichion does a super job in keeping the room toasty so you can get your sweat on. They also offer a variety of classes and times which is great.
Cons- You will be crammed into the yoga room like tuna in a can. They have tape on the ground that outlines where to place your mat, I believe in an effort to maximize the # of ppl in the room. I couldn't do some moves bc of the awkwardly close proximity to your neighbor. It's a turn off. Lastly, for someone who hasn't done yoga or hot yoga before, there's not a lot of instruction or personal attention as other places offer.
I appreciated my classes but I wouldn't go back again.
