re: What to do on the day of the wedding for groom/groomsmen?

When I was younger in weddings we would always want to do stuff during the day before and would end up rushing to get ready or someone would always go a little too hard. Once I hit my 30s most of the weddings I've been in including mine we just had a casual lunch in a suite at the hotel and chilled and relaxed while drinking a few beers and hanging out. Keep it simple, its will be a long night and everyone will have more than enough fun.
