We absolutely adore having DVC. Our vacations are more relaxed now because we know we will be back. The rooms are gorgeous. We enjoy staying at the Deluxe resorts. We own at Boardwalk and love having the boardwalk view and being so close to Epcot and Hollywood Studios. We love being able to take others with us. We love being able to still go on vacation when money is tight. My sister and brother-in-law love going with us and staying at the Beach Club Villas.
We go to WDW much more than before we owned DVC.
I would personally be a little apprehensive about joining DVC for a trip every 3 years. A new job, a new baby, or an extended illness could come up and then you would lose 3 years worth of points!!
DO consider trips at least every other year for that purpose and buy your points accordingly.
If you plan to go less than once per year, do plan to go early in your UY, so that you can regroup if necessary.
If you have a fixed date vacation every year, (My Brother-in-law only gets the week of the 4th of July), then PLEASE do not purchase DVC to use every 3rd year. Things happen!!!
We had originally planned to use DVC every other year, and now average 3 trips every 2 years, plus trips to Hilton Head, South Carolina.
