Bachelor Party Booked

While I am planning my trip to Vegas with my girl for our bachelorette party, I am also booking the flight for Joe to return home for his bachelor party. We figured since all of the groomsmen are from Philly, and it will be costly for all of them to fly out here (if they can make it at all), so it's easier for Joe to go home and see his family, while being able to party with his friends in Atlantic City or New York City or wherever his heart desires. I will have no part in it except to book his flight and car rental. It's booked. He's scheduled to go the weekend that I have my bridal shower. He'll be in Philly from 1/29-2/2.
