I don’t go in Naperville, but costs are the same everywhere and I also pay the $149/mo for unlimited. However, i think the price went up not too long ago. You get to keep whatever cost you had when you signed up, but I think unlimited is $159 now. They do an 8 times a month and a 4 times a month for less. Your first class is usually free and they explain costs after to you. Go try one. I love it! I’ve been going to almost 6 years
