Some class times are more popular than others, if you prefer small, try all our afternoon/ evening times. You can reserve ahead, so you are IN. Please no phone. If you see that a class is no longer available for online sign-in, it doesn't mean the class is full just that the signup period has passed or we have reached our limit for pre-registration. Arrive 15 mins early you just may slip in..We do try to save some spots for walk-ins.
