I just paid my annual MFs this morning (after all, why pay early?). Here  are the details, and also some comparisons. I'm sure some of you may  find this of interest.
Of these weeks, it's obvious to me that my "affordable" and "great  trader" of SVR is taking the largest hit this year with a whopping 25%  increase. Of course, it only had a 2% increase last year. Also, I list  my two SVR Falls weeks separately so we can all wonder how/why I have  two different MFs and different taxes. This may be the year I readjust  my timeshare ownership.
WMH and WKV, in my opinion, were good to owners this year with minor increases.
