tmela808's Blue wedding

We are having 3 dinner options for our wedding (fiances choice)...Chicken, fish, and beef. How do I go about this with place cards? Different colors, ribbons? And when you put Mr. and Mrs. so and so and they want two different food choices, what do you do then? Then there is a family of 6 coming 2 parents and 4 kids, do I give them each there own place card? or since they will basically take up almost a whole table just say the " " family? Im so confused on how to go about place cards with the waiters knowing whos getting what, like with couples with one place card, how do they know which side there g/f,b/f or spouse is sitting on? ahhhh meltdown! Help! lol
