We started out with 175 points at OKW for the three of us. We also thought we would only use a studio once a year. But we bought our points for the times of the year when we knew we could get our son out of school. The first trip we took, we took my husband's parents with us, so we needed a two bedroom. Well, that shot those studio plans. We loved having the extra room, the washer and dryer. It was going to be one bedrooms from there on.
So we bought a few extra points, 75. Now we had 250. And we decided, hey, let's go in the summer, too. We could stretch those points for two trips including at least one in a one bedroom.
All that said, we now have 500, use them every year and have a ball. We're even thinking of using points at the Grand Californian for next June if we can. We'll be borrowing from our 2006 points to do it since we are out of 2005 points (Sept use year).
I'd say 180 is a great way to start out. Welcome Home!!
