How do you group guests at tables?
We're working on a preliminary seating plan that obviously won't be finalized before rsvps are collected. But curious how to seat people when there are overflows of family and friend groups that don't fit evenly at tables for 10. Some family tables would be 4 or 6 people while separate friend groups would be 2- 6 that don't necessarily fit with others as "seat fillers" but they may have something in common. How do you go about this without being awkward for guests? At the same time, we don't want extra tables where 2 people sit by themselves which is uncomfortable and unwelcoming.
We are also planning a large table to be able to sit with attendants and their partners we don't get to see often rather than on display at a sweetheart table.
Edit to add: there are a few friend groups of 2-6ish people mixed in that won't know anyone other than us but are important to invite. We don't know how to fit them in to other tables without putting them at their own table which spotlights them instead of mixing in.
