I have found that with overlapping ones, it works as long as the lead guest is different,
When we went a few years ago, I booked an extra night for my DS and DDIL at VGF while we moved from BWV to BRV.
When they got to VGF, they just checked them out of BWV and into VGF. When I checked in to BRV, the CM just unchecked their names for that night and then the next day, checked them back in.
