we own at SSR and have never stayed there. I go in Sept. with my sisters, we always stay at BCV and have never had a problem.( We go for opening Food and Wine)
October we go usually with friends, and again BCV, for food and wine and mickey party. This year we were waitlisted, and it came thru as a split stay, BWV first 2 nights, BCV last 2 nights. This is the first time we didn't get all at BCV. Took us off waitlist, because group thought they would like to try BWV.
We book at SSR on our 11 month window, then call at the 7 mo and switch. It is easy for us to plan, we go just about the same weeks every year.( Just the 2 of us now, easy flight from Richmond, so not too costly our AP is our Christmas present
Also have had no problem in Feb, or may for flower/garden. No problem early Dec either,,we go week before Christmas, leave around the 21st.
I would love to add on at BCV , but DH wants to buy Mariott points for next purchase. We really Love the Mariott at Hilton Head. We went to the DVC at HHI, and ended up spending a lot of time at the Mariott.
