I had been watching the WLV on the RAT the last week and noticed that every day by 9 the corresponding 7 month date was gone, but everything after that would still be available. I was getting discouraged since I needed to cancel an OKW reservation to have enough points to book at WLV
and so needed to wait until 9 , call in and talk to a CM to cancel and book. What worked for me was this: I was online right at 8. By the time I was in the site, my room was gone for the first night. However,20 minutes later it reappeared! I had enough spare points to book just the first night. Then at 9, I called MS and cancelled the original ressie and added 5 more nights to my now existing one night reservation. I know an owner could have grabbed those days before me, but that was not the booking pattern I had observed. The cm even said how smart it was to grab that first night online. it made it possible to complete my reservation , even though I needed to wait until 9 to call.
