Seating Chart Arrangement

How are you arranging your seating chart?

Alphabetically? By table number?

I was thinking of doing it alphabetically by last name that way people aren't trying to search for their name for a million years. If you were a guest, which would you prefer? Personally, I prefer the alphabetical, but I want other opinions because I'm biased haha.

So, instead of:

Table 1

John Smith

It would be:

S

Smith, John..........Table 1

Example of what I mean
