The advantage is the 11 month reservation priority at your home resort.
It appears that you own at HH- which certainly provides a good advantage for you to reserve at that resort during the popular summer months, but you might experience a challenge getting a BWV reservation for Thanksgiving - 7 months in advance.
For many people, the 11 month priority is important in planning their vacations. For others, the 7 month schedule works fine.
Enjoy!
