You will receive an email with details of the vacation you’ve won. You have 7 days from receipt of the email to activate the vacation by paying the taxes and fees. If you do not activate the certificate within 7 days of receipt, the certificate will be void.
Once this is done, you will get an email receipt and links to redeemvacations.com confirming the vacation is activated and there is nothing further required until you want to make the reservation.  You have 18 months from the receipt of this email to search for dates and choose from participating hotels based on availability.  The process is all online.
