I’ve experienced the same recently on the Silvers since the return of traditional dining. Some LSAs require communal seating and another seating parties at their own table. Given the number of people eating in their room the latter seems the better way to do it for passengers. I don’t find sitting at my own table a hinderance to socializing. On my most recent trip where I was given my own table and they spread people around the diner I just chatted with people at the adjacent table the same as I would with people at my table.
