No regrets whatsoever. In addition to the family vacations, my wife and I have taken a few long weekend getaways at OKW and Grand Floridian. When we haven't been able to use our points, we've easily rented them through DIS. This year, we were dead set on 4th of July at the beach. Vero and HH were booked, so we rented some points and are using the proceeds toward a beach house rental nearby. The remaining points will be used on a 2br for four nites at VWL during Columbus Day weekend.
So much flexibility with DVC. The quality is always excellent. I highly recommend you go for it!
