Activity for Blaine

I need some ideas on how to indicate what my guest meal choice is on their place cards. There will be three total (Chicken, Pork and Kids), my colors are purple and grey. I don't want to just put a C, P, K on them but I want whatever I decide to do...

Are you planning to have your cake table in front of the head/sweetheart table? If so, is your cake going to be displayed all night? I'm not sure if I can trust having a $400 cake on display for a few hours before we cut it... what if someone knocks...
