We do the same on our measely 150 points for a family of 3. It all depends on what you are looking for when and how frequently you visit.
We have a family of four, 150 points, and have plenty of points for a two bedroom in October every other year. Because our kids are young enough for the hideabed, that's enabled us to bring guests - or move to a one bedroom and save points - we are getting two two bedrooms this October using three years of points (and avoiding weekends) for a family reunion trip.
Granted, if we wanted a two bedroom for a week every year, we'd need twice as many points. Or if we'd go in the summer or over the holidays.
Remember dues - that dues bill comes around every year and makes me gasp at my mere 150 points.
We, too, are currently looking at how many points etc. This has been a wonderful thread to read.
