Moab Man offers good advice, you need to practice/study posing. I trust you already know camera mechanics, DOF, low light, stobes etc. Then, practice some patience, ability to accept suggestions and when necessary demonstrate who's boss when it comes to the pics and be tough enough (without creating hostility) to capture and control your space. When you get everyone set for a shot, that's when the peanut gallery with phones, cameras, camcorders will appear and diplomacy will be your best friend and companion. It can be fun if you can establish a good rapport with your clients and respect from the guest that mean well but interfere a lot. Good luck...
