Our kids are adults now, so we're actually looking at it from the perspective of indulgent grandparents.
There are a lot of pluses that go beyond the extra space. A 2BR villa guarantees us that the kids and grandkids will be in an adjoining room. There's a full kitchen to accommodate everyone's mealtime preferences. Having a washer and dryer in the villa is priceless.
We create our own CL by ordering alcohol and appetizer platters from DizzyDolphinDelivery.com If you've never heard of them, check out their FB page. Their stuff is amazing and is head and shoulders above your average grocery delivery service.
We used to do CL prior to owning DVC and I have to say that I much prefer having DVC. The only downside is that unlike booking a Disney CL room every once in a while, DVC ownership has pigeonholed us into taking Disney vacation pretty much every year. Up until this past year, it wasn't a huge problem because we could rent our points out pretty easily. This was the first year when we didn't feel like using our banked points where renting them out was more difficult.
