Hey ladies. I'm co-hosting a shower for my SIL in a couple of weeks. Her mom, who is not involved with the hosting, was surprised that we were not planning to have assigned seating. I figure 35-40 women can figure out where they want to sit without guidance. Besides, not knowing every guest makes it a little hard to determine where to put them. But am I wrong on this? Is it gauche to not have a seating chart?
