You may be missing something small [and hidden in the website structure].
The RCI Points search engine stinks and recent updates have made it worse.
Here is a crippled way to search individual resorts.
1) click book at the top of the page
2) Then click "exchange vacations" under search.
3) You will then get this screen where you can search by resort name or number.
It is ridiculous and sad how clunky the website is, AND it is getting worse instead of better.
The box at the very top of all the screens that says "search for your next vacation" is really an endless tree branch style listing with not much actual "search" function.
It also used to be easy to have "favorite" searches and resorts saved, but that feature is really messed up at this point of the company's web (de)evolution.
