I see what you mean. You search by area first, then have to choose a specific resort from a list.
I search for a specific resort, like Hilton SeaWorld, then I can see the costs as I scan down the list of dates.
The way resorts are listed in Wyndham is so different from RCI weeks and points. BUT Wyndham doesn't get discounts for much of the inventory, while weeks and points get discounted inventory. It's really quite strange that Wyndham owners have to pay full points for something within 30 days, and weeks will be reduced by half TPU's (or another significant discount), and points will be 7,500 ($82 cost for me).
For example, there are some Hilton SeaWorld that are 165,000 Wyndham points + exchange fee (and resort fees). That is the regular price, not discounted, but they are close to check-in date. That same week might be 9 TPU's. 9 TPU's is about $450 my cost, 165,000 points is about $950 in my cost.
One shocking exchange that recently came available was 25,000 RCI Points for November, 7 nights, Wyndham Avon, 2 bedroom units, all presidential. It was somewhat discounted in Wyndham's RCI portal, but not enough to come anywhere near my cost in RCI Points.
