Parkwood houses are literally always having parties. It's got to the point where if I can't hear something going on at night I suspect nuclear bombs have been detonated around the place but it was awesome for meeting people in freshers. I'm in the flats (ground floor, facing in to the 'courtyard' bit) and we have a few parties but as the houses open right out onto the paths they're mostly there. Flat parties require two doors to be held open by something/one and it's a bit of a pain. House parties are also dead handy if you happen to be bursting for the loo on the way back from Venue or somewhere and need to make a quick dash as I've found on multiple occasions. Bless Purchas Court and it's bathrooms.
Venue is also really good, cheap Jagerbombs before 11pm and free entry before 10! Pre-drink and you're good to go.
