Planning to stay 4 nights in Feb 2018. Only have 88 points. My home is Poly. Would you book 4 nights standard view for 84 points or book 3 nights Lake view for 75 points and hope to add the 4th night at the 7 month mark by purchasing OTU points? 4 nights in a lake view is 100 points. I'm worried that the 4th night may not be available at the 7 month mark. We really want the lake view. TIA!
