A schedule like this is not possible, it would be better not having byes and sending 4 teams to each site.

Unfortunately, this happens after school and a time issue have 4 teams at each site. Any other thoughts?

If we compromise on the format a little and sometimes only send 2 teams to a venue, then it can be done in 6 rounds.

    Site 1     Site 2       Byes
  (4  2  3)  (6  7  5)    [1  8  -]
  (3  8  -)  (1  2  5)    [4  6  7]
  (3  7  1)  (5  8  4)    [6  2  -]
  (4  1  7)  (2  6  -)    [5  8  3]
  (3  5  -)  (1  6  8)    [7  2  4]
  (8  2  7)  (4  6  3)    [1  5  -]

So above team 3 has 1 bye while the other teams have 2 byes each. There are also two repeated games in the schedule, so:

In round 4 the match up between teams 1 & 7 does not need to be played.
In round 6 the match up between teams 3 & 4 does not need to be played.
