As other posters have said, it's all relative to your preferences. I've seen people post that they booked a 2BR for a family of 4. That's probably not a 'good' use of points, but saves their sanity and I'm sure they have tons of fun!!
We used points for a cruise 3yrs ago, still get sentimental when I walk by the pictures of our kids up on our wall. Have fun making wonderful family memories.
