Nice! We’re looking forward to the invite. ;)  Seriously though, this is a great question and when not handled appropriately, can be a tough issue. The most important thing here is that you attempt to house as many of the vehicles on your property and when that is maxed then then have your guests park as far off to the side of the street as possible. In most cases keeping everyone to one side of the road is helpful. Lastly, if you are comfortable doing so you may want to give the community a shout via email to let them know there will be guests on the street to keep everyone involved safe.
