Should i have a seating chart?

I would always opt for a seating chart. It's less awkward for guests and will save you money in the long run. Without a seating chart, you will need to account for 20% more tables, seating, centerpieces, etc. since guests don't seat themselves efficiently. I also think it's fine to have a kids table for them to do activities, but they should be seated with their parents for dinner.

I'm the oddball on this site. We are going the no seating chart route. For us, it's a "know your crowd" thing. My people are all plenty capable of finding a chair. We are also not having many large numbered groups mostly just couples. Those with larger families are my siblings that will be at reserved family tables.
