I usually don't call day by day during the 11 month booking window. I think this is because we own at SSR and there is really no need. Even for March spring break 2009, we need a GV. I called and booked it all at once.
At seven months, if I want to switch out, then I usually call day by day. We have BWV for last week of Food and Wine and I had to use waitlists to get that. No worries. Now, I don't need the Boardwalk View so maybe that is why it works for me ?
the other issue that I just thought of is the SSR has no booking categories and plenty of rooms, so day by day is definitely not necessary during the 11 month booking window. Maybe that is why my experience feels so much different that others who, for instance, want Boardwalk view of Hospitality House at OKW.
