The answer to your question really depends on how the Wyndham resort you're looking to buy is deeded - - is it a fixed week or points? All fixed weeks units have a point value for those who want to go there, so the points system allows them to do so.
Example of what I'm speaking of . . . I own a fixed week (#18) that is a 3BR lockoff. If someone were to want to stay there using their Wyndham points, it would require 203k. If someone just wanted to stay in the 1BR side, it would be something like 77k and if they wanted the 2BR side it would be something like 126k.
If however I own a timeshare within the Wyndham system that is sold and deeded as 203k points, I can use those points however I wish.
Lastly fixed weeks owners can convert their week of ownership into the more flexible points system for a price. For me, converting my fixed week into the 203k points it would be valued at is just not worth the added expense.
Since I really can't tell what it is you're looking to buy, it is difficult to really answer your question. I guess the short answer would be *if* it is a fixed 2BR week and you only need 1BR, and it is not a 2BR lock off unit, you really can't use just the "value" of the 1BR and use the balance in some other way. Conversely, if it is deeded and sold as points, yes you can use what you need for a 1BR and do something else with the balance to points you own.
