I came here about the same thing hahah. I’ve been trying to book my December 23 trip at RIV since Monday the 2nd, and every morning, what should be the first day of my check-in is booked up BUT the rest of the week is available. But since the next day is outside my booking window, I have to try again the next morning. It’s almost like people keep adding on 1 night stays to a reservation.
I called member services to ask if I’m doing something wrong, figured there’s a few tricks I’m not using since I’m relatively new to being a DVC member but I’m doing everything I should be doing.
However, Member services explained the “walking” tactic that some people use, and unfortunately it looks like that’s what’s happening here. Guess I’ll just have to start doing the same tactic since I’m just being left in the lurch

.
I waitlisted the entire length of my stay for now, but going to keep trying to have something confirmed. Hopefully the “walkers” will just keep “walking”right past my reservation dates.
