I just added on a 50 point resale. It was in the same use year as my 3 other contracts. It was "tacked-on", as you said, to my current contract(s) and all are accessed via the same membership number. I know that this contract was posted on the internet for less than a day, so they do go fast. Let a broker or two know what you want and they may contact you even before they post it publicly. I have worked with Shontell as well as Jerry at the Timeshare Store and recommend both highly.
