I can't remember thistle playing more than two games over the festive period, certainly in the last 15 years or so.
Edit: Shows how good my memory is, we've played three games as recently as the 2008-09 season.
2008-09 - Sat (27), Tue (30), Sat (3)
2005-06 - Mon (26), Sat (31), Mon (2)
2004-05 - Mon (27), Wed (29), Sat (1)
2002-03 - Thu (26), Sun (29), Thu (2)
2000-01 - Tue (26), Sat (30), Sat (2)
1996-97 - Thu (26), Wed (1), Sat (4)
1991-92 - Sat (28), Wed (1), Fri (3)
Every other season since 1990 we've played 2 or less games.
