There are several guests of friends that I either never met so don't know their name (I'm not sure said person even knows who they are bringing yet) OR I met them maybe 3 times so I know their first name (not sure they know mine though) but not their last. SO on the escort cards do I say Jane Doe party Table 1, or Jane Doe and Guest Table 1, or Jane and Jon Table 1. Is it necessary that I determine everyone's name?
