With StarOptions, you have the flexibility to exchange your Vacation Ownership Interest (VOI) for a stay at another VistanaTM Signature Experiences villa resort—without any fees. To help you plan the perfect vacation, our StarOptions Values Chart breaks down the weekly and daily StarOptions required to complete a reservation at each VSN villa resort, Villa type and Season. Remember, weekly valuations are calculated based upon a Friday arrival only. If your dates of stay cross over into another season, additional StarOptions may be required since StarOptions are calculated based on the Season of each day of your stay
