From Vistana Website:
Vistana Signature Network™ (VSN) reservations made during the Home Resort Reservation Period or the VSN Float Period are subject to the following cancellation policy and may be canceled by calling Owner Services prior to the arrival date
of the assigned reservation. Failure to cancel a confirmed reservation prior to the arrival date will prevent the restoration of StarOptions® or Home Options for further use.
Reservations may be canceled 61 days or more prior to arrival with no cancellation fee or Usage Restriction.
Reservations made 60 days or less prior to arrival may be canceled through the following day after making the reservation (before the end of hours of operation, Eastern time) with no cancellation fee or Usage Restriction. After this grace period passes, cancellations and modifications to the reservation — including changes to the arrival or departure date or to Villa type (other than releasing one side of the lockoff for reservations confirmed during the Home Resort Reservation Period) — will incur cancellation fees. Subsequent usage will be restricted to reservations within 60 days of the new requested arrival date for that Use Year and will not be eligible for StarOptions Banking or loyalty points conversion.
I would call as soon as possible
- 60 days–8 days: $50 cancellation fee
- 7 days or less: $75 cancellation fee
