I Have a BWV studio booked 3/14-3/17 and VGF studio booked 3/18-3/21. I would take either resort for the night of 3/17 but neither is currently available. I want to keep the split stay, just 4-3 or 3-4. I created two waitlists, one for BWV 3/14-3/18 of the same room type, and one for VGF 3/17-3/21. Both are set to replace the bookings at the same resort, just adding the extra day. Is this an ok way to do it, and Disney knows that my 3 existing nights will free up along with the 1 additional night to fulfill the waitlist? Or do I HAVE to do 1 night waitlists then merge them later? I was hoping to avoid the extra merging step, but if they won't fill because of the way I did it, I will go back and change them to 1 night waitlists. Thanks.
