Need help with a strange situation

[LetsPlay1969]

We had a 12 player freeze out home game divided into two tables of 6 with the tables combining to the final table at 10 players.

In the past we draw for seats and put chips in play for any player arriving late. Their hand is mucked after it is dealt and the blinds lost.

Usually we don't have many late players and the empty seats by luck of the draw are evenly distributed. But last week 4 players were going to be late and as luck would have it they were all at one table leaving us with a full table of 6 and a table of 2 with 4 empty chairs.

The players at the full table wanted a re-draw and the two players at the empty table wanted to play.

What is the ruling?

What would have happened if there was only 1 player and 5 missing?

Thanks
