Dreading the Wedding

One of my oldest friends is getting married next weekend and I'm one of the groomsmen. I couldn't be happier for him and I couldn't be more honored to be included in the wedding. I should be excited, right? Here's the problem: I've also got a show in Atlantic CIty next weekend. I'm not sure how I'm going to handle it - I have six hours of rehearsal on Friday afternoon, then drive down to the casino, check-in around midnight, wake-up Saturday and sound-check/rehearsal with the singers (usually lasts all day), break, dinner, then the show from 1AM to 3AM, pack my gear, change get back to NYC somehow, hopefully by 6AM so I can sleep for four or five hours, shower, dress for the wedding and meet the wedding party in manhattan at noon, pictures at 1:30, ceremony at 4 and reception following. It's going to be really hard, I'm already dreading it.
