Timeshare ownerships where the owner can travel every three years.
In the timeshare world, triennial ownerships are ownerships where the usage is available every three years rather than each year or every other year like with annual and biennial. These ownerships work exactly the same way as other timeshare properties but with less frequency. Triennial owners will still be able to use their ownership weeks earlier than the scheduled date(s) but it will be borrowing the time and the next week will not be available until the next cycle.
Once the ownership has been purchased, the likelihood that you can change when your useage year is is going to be very tough or impossible. It is crucial that you make sure that if this is the type of timeshare you are going to purchase, that it fits your lifestyle and timeshare needs.
