The only way to get points is by buying a deeded week. Deeded weeks have different values based on resort, size and season. Your recently purchased week was a deed that had a corresponding value of 11,200 points. There are some deeded weeks, primarily Hawaii, that have more points attached, such as a 3 bdm platinum worth up to 36,800 points. Buying that direct however would likely cost you upwards of $175,000, if not even more. You could “trade” your existing deeded week for another but HGV will still extract tens of thousands of dollars from you.
How many deeds you end up with buying direct to get elite will end up costing significantly more than the value of elite. If you have the money, and don’t mind paying tens of thousands or even hundreds of thousands of dollars for something that would be worth maybe 20%-30% of what you paid immediately after signing, then that is a decision only you can make.
