Yep, I think having it as a day function is the key... they seem to get more reckless at night. Last time they all had plans to go to the MCG for a night cricket game so they all choofed off at a set time... it was great. This time I might suggest they go and see the locally famous Christmas lights display... just so we don't have loiterers after dark. Also means i MIGHT get a chance to go to the BB Chrissy Dinner afterall!
