Just a friendly heads up....
With only 75 points, I am making the assumption that you are planning to book mostly studios. Over the past few years, the popularity of studios has increased dramatically as the rental market has flourished. Studios have become very popular and availability can disappear very quickly at 7 months, or sooner depending on when you are planning to travel. Be prepared to book at 9-11 months out on a regular basis in order to secure a studio. If you plan to book more than 3-night stays and you must wait until 7 months out, be prepared to be flexible and know that you may need to use the waitlist or perhaps split your stay between different resorts. I am not saying this is going to always be the case, but it is just a friendly "heads up" because it has become more and more difficult to book studios at ALL times of the year. When I see new buyers looking to purchase just enough points to get a studio, I cringe because I fear that when they start to have trouble finding availability, they will see their points going to waste and that makes for a very unhappy owner.
