Best use of points is whatever works best for your family.
When we became members 9 years ago (my, how time flies!), we had a baby, and stayed exclusively in studios as we only had 175 points. We ate all of our meals on property.
We then had a second child 4 years later, and added on 185 points to stay in 1 bedrooms, as we were tired of eating 3 meals a day in restaurants. Love the full kitchen and laundry room!!!
Fast forward to today...hubby and I just made an important decision based on the needs of our family. We have decided to upgrade to 2 bedrooms for the 4 of us, as we need the space. We have a daughter and son, who are 4 years apart, so sleeping arrangements are very critical around here. Studios don't work, except for 1 night (1st night, as we usually arrive late afternoon, go for dinner and visit park) - had a very difficult trip in March in a studio for 6 nights.
I am sure that many people will think this is a waste of points, but as we looked at the
point charts, we have realized that there is a big jump between studio and 1 bedroom, but not so much between 1 bed and 2 bed, so for us, this usage of points will be best for us, as it will allow everyone the space and amenities they need to be most comfortable for an almost 2 week stay each summer.
We will do a small add-on (can't believe it, as I said no way!), and we will be able to do 9 - 10 nights each summer in a 2 bedroom. We are pretty sure the kids are going to love having their own room and extra bathroom, and so this usage of points will be well worth it, as it is necessary to keep our Disney family happy!
