Have owned for 13 years. Definitely do not see us selling anytime in the future. Of course - will never say never and family emergencies (medical, financial) can happen anytime to all of us.
I have also met and know many
DVC families here (where I live) and I know of two who do not use it every year. They also just pay their dues and go when they feel/can go. Just like owning a second home on the shore, the mountains. You take care of it, pay the expenses and go whenever you can/want.
