I would like to play it like this- the kingdoms are not too far from each other. Over the years they girls have gotten to know each other (through royal balls, teas, etc.) SO each of the princesses would have been to each others castles a few times. Some have already gotten that wandering eye, but many of the girls don't realize that their friends feel the same way they do.<br/><br/>The castles shouldn't be more than a half days ride from each other- that way it gives them time to sneak around.  How does that sound?
