If I pay for a 3-Week Intensive, Weekly Class, or Workshop and cannot make the session, can I receive a refund or apply it to another session?

No.  Due to the small student limit in each Tango Intensive, once you pay tuition on a Tango Intensive your spot is reserved FOR THAT SESSION ONLY.  You may, however, give your spot to someone else of the same ‘role’ (‘leader’ / ‘follower’).
