Table numbers and place cards. Yes or No

Val

Finally after waiting forever. Everybody RSVP for my daughters 1st bday. Just 2 people said no, what brings the count to 62 adults and 25 kids. I rented a hall for weddings. it will be BBQ style food. Games and entertainment for kids.

It's 4am and I'm questioning myself if I should have place cards and table number. I'm not looking on anything fancy.(with kids between 10m and 12 yo that's impossible). Do you think that's ok? or it will be a disaster? Also I had planned just having 6 tables. I guess I need to add 2 more.
