1) You will end up with at least two tables.
2) How near each other can be a problem.
. . . one may be close
. . . one may be further back in the eatery
3) Also, the seating time may not be the same for the tables.
. . . not all tables are ready for seating at the same time
. . . some tables just get empty faster than others
. . . so, part of the party might get seated and finished before the other
