I've only even been to weddings with assigned tables but I am contemplating assigning seats. The reason is that I am using rectangular tables that seat 8, and pushing them together. For example, tables 1, and 2 are really like one large table that sits 16. I was thinking that when I group people together I may have a group of 10 and a group of 6, so I'd want those 2 extra people to be sitting where the tables meet. Make sense?
Have you been to a wedding that assigned seats and not tables? How did it work out?
