Unfortunate you have to buy at least one more time to ge to VIP.
That is why I feel all the risk associate with retail purchase compare to any resale purchase. And sounds like at this moment, your 154k is a retail purchase product. So you are 146k away. Most method I know will automatically require you to make a 77k retail purchase to start with. Even if you want to become gold VIP, that is still not very cost effective.
You can buy resale point, have them do equity transfer so all the points look like is from retail. Of course, there are all kinds of rumor it is illegal, and people get strip out of that. Plus, they sure will ask you a lot of extra money embeded with your purchase. Originally, you may be able to get from say 100 per 1K instead of paying 200 per 1K their asking price, now you may actually paying 190 per 1K and think you are getting some good deal.
You can also buy a convertable week, several of them (no more than 4), and convert it without buying any more point. It may or may not count
You can also buy a week or 2 outside of Wyndham but exchange with RCI ad not in any point system, and buy some points from them, and bring these week(s) in. The problem is, once these week change to point, or if you want get rid of these weeks, you loss the VIP status.
The best way is to learn how to use these points to its max before you decide what is your next action. Then if you really want to get to VIP, you will know exact what it should cost you, and you can set the price, and ask them to match it.
