I have to agree table assignments are a waste of time. Really I enjoy being at weddings where I get to decide who I want to sit with. Not who I'm forced to sit with. Just assign 1/2/3 tables for just family or really close friends who you want to sit by the bride and groom table and let everyone else sit where they want to. I went to a wedding where my friends were across the room and I got stuck sitting with my honeys friends, who are nice but I would've prefered to be able to be near my friends also. And it's less stressful to not have to worry about who likes who, and who knows who, etc. Good luck!!
