Steve,
Last night, I checked every Wyndham facility in Florida. First, I did a search for the whole state, then by area within the state, then each individual resort. Most are wiped out for the entire week. The best I found was a couple of single nights with night in between that is not available (e.g., Wednesday and Friday are available, Thursday is not).
March 19 is the magic "15 days before check-in." That's the last chance for Wyndham owners to cancel unrented or unusable reservations. Something may pop up then if you haven't already arranged something.
