I booked my lodging yesterday and was surprised by that final total with an additional $15 a night fee as well as the higher taxes due to the higher base price. I have now found where it is listed, but it's not obvious (at least not to me!) so I wanted to point it out for anyone still working on budgets/proposals for attending. In the pop up for "more about this rate" (pictured below) at the top of lodging page is where you can find mention of the $15 fee.
But this fee isn't included when you click "view price breakdown" on individual rooms (see its pop-up below):
Hope this helps someone not make the same mistake I made
Oy vey, the dreaded resort fee! I hate that!
