Accrued weeks or points are the vacation time that has been saved from previous years, which will accumulate and are still available for use by the timeshare owner.
The ability to accrue, or bank, your week is a resort specific feature. Meaning, not all resorts or clubs will allow you to do this, and almost all of them have restrictions. These restrictions can include, but definitely aren’t limited to: a cap on how many weeks can be saved, how far out you can use the weeks/points you have banked, whether or not accrued weeks can be used for trading, whether or not accrued weeks/points can be used for other special programs such as the Hilton HHonors. Many clubs allow you to use your weeks or points up to 2 years from the date you can start booking your points, or your 2 years from your week number.
This can be coupled with banking, also known as space banking, as well. Space banking uses an exchange company to extend the life of your points. The most popular exchange companies will take your deposit of points or weeks and honor them as valid for up to 2 years. Meaning, you will be able to book a week from the exchange company’s inventory for up to 2 years from the time you deposit. When combining the time your resort or club offers to accrue your weeks with the exchange company’s 2 year banking, you can sometimes save your weeks or points for up to 4 years.
