When checking out of WLV, have the bellmen take your bags and ask them to transfer them to BCV. Once you've done that, continue on with your plans for that day like going to a theme park or water park. Your bags will usually arrive around 3:00PM at BCV. By 4:00, I would say you could just hop on Disney Transportation for BCV and your bags will be there. Of course, you could stay out all night and come back, but bags are usually transferred and at your hotel by 3:00PM.
