That's a busy time of year so I would assume early check-in probably will not happen. My husband and I went Dec 10-16 to BWV. Our studio wasn't ready until after 5:00 pm and that's supposed to be a much less crowded time of year. One can always hope though!
We are three for three on immediatley having a room - though it hasn't necessarily met our "view requests" We got into a BW View room at 1:00 - but it was Handicapped. We got into a SV room at 3:00 - but it was on the ground floor when we requested high floor. We got a preferred view room around 4:00 - but again, handicapped.
Our best was at the BCV two years ago a few days before New Year's. We checked in at 10:00 A.M and were told our 2BR was ready. Talk about a shock. But a year ago at the BCV we waited until 5:00 P.M. and ended up having to change rooms. You never know what will happen. You may get lucky (or you may not).
we have gone in august and called early in the morning from the hotel we were staying overnight at and they told us they had several rooms available and to come as soon as we can.I believe we were all checked in by 11:00am My dw just said it was the third week in August.Good luck
