That's okay! You should still pre-register. You can always call or email the studio to update your availability. Pre-Registration ensures that you're counted in for the next dance season!
You can Pre-Register with a deposit of $50 if you're a single-dancer taking one class or $100 if you're a family or a single-dancer taking more than one class.
You can always switch to another available class, or if you can't make the schedule work, your deposit is 100% refundable.
