Just remember all the military folks in uniform (hopefully not the groom) are going to get piss drunk and look like crap in their uniforms when the night is over (hopefully if the wedding is that fun). I went to an Army wedding in SDBs a long time ago fell back in my chair a number of times, rode the elevator just for the fun of it and got scolded by hotel security to not inhale the helium balloons from the high school prom in the other event center. I woke up not remembering a darn thing and my wife being very mad at me. I wasnt happy getting emailed pictures of a bunch of military OFFICERS in dress uniforms inhaling balloons and throwing lawn furniture into the hotel pool. But damn it was fun.
And if there is a sword arch, beware of sword fights breaking out at church.... and the reception!!!
