I totally understand. Grace goes into kennels whenever there are going to be too many people around for her comfort and (maybe for safety), large family gatherings with tinies especially. I always feel dreadful about it, but she is perfectly content there, I can relax with tinies around and there are no accidents (in our case more of the stolen food variety) It doesn't help your conscience if that is the reaction. Your dog will have a lovely peaceful time, there will no doubt be leftovers to come home to and she won't be pestered by an over-enthusiastic puppy.
I'm right behind you!
