I just bought the pack a few days ago and I've been enjoying it aswell! Only issue is that townies in my world don't seem to understand the difference between "spa" and "club" and they keep coming in and doing nothing but dancing to the relaxing spa music :s
I really like the vibe of the pack, we don't really have anything Asian inspired in this game yet and I love that kind of style so it's a refreshing change! I found a Japanese spa build on the gallery with a yoga garden and a massage hut which has been really nice to send my sims to. And I love how there's items that I can use in my home, the "locker" looks more like a wardrobe and it works perfectly as a wardrobe in my home and I like how it adds more options to the regular bathtubs, also my sims been doing yoga on the roof now which is fun!
