We're having our Dancesport Club social in Halo (right next to uni) - apparently is their biggest and longest running Hallowe'en ball. We're paying a £1 entry, no idea how much normally, wouldn't have thought it would be much though.
if you live in a unite complex. i live at James Baillie. we are payin £8, drink all you want for 4 hour then a ticket to Baja which gets you a Q Jump and free entry! basically, everyone at James Baillie will be hammered!
