After chewing on this for another night, we decided to simply go with the week that includes FC access. Here is in the closing document that we just signed this morning: "...In addition to closing costs, Purchaser shall pay at closing (or be billed after closing) the first year's maintenance fee, and Club Dues, which are payable separately of $45.11 per week owned for US and Canadian residents and $79.61 per week owned for all other countries),...."
In a separate sectioon: "The current year's assessment for common expenses allocable to the timeshare interest you are purchasing is $1,259.22. This assessment, which may be increased from time to time by the managing entity of the timeshare plan, is payable in full each year on or before JANUARY 2018. This assessment includes yearly ad valorem real estate taxes, which are not billed and collected separately...."
I conclude that $45.11 is the Florida Club dues.
