I own a different Starwood 2BR l/o but I imagine it works the same way. After you log in, click on exchange (the default is Getaways-- you have to click on exchange). Fill in your search parameters. The next screen directs you to select which of your units you wish to use to search. My choices are: 2 BR, 1 BED A, or 1 BED B. Since I can never remember which side is A or B, I just click "select" on 2 BR. The next screen asks you which portion of the lockoff you want to choose: the 2 BR master unit, the 1 BR full kitchen, or 1 BR limited kitchen. Now at WKORV, you have a studio side, so I'm guessing it will say studio instead of 1 BR limited kitchen, so you may not have to do that extra step. After that, it will bring you to the search results. You do not have to deposit anything in order to search.
