You are more or less there. Most people take an air bed too. Take a mug for brews if you drink tea as someone will always have a kettle on the go and might share tea bags. I usually take more stuff than I need but better to be prepared Foodwise, there is usually something open early until late, the noodles used to be epic, but have gone downhill last couple of years but there will be something decent to eat. Bring plenty of snacks and crap to munch on Drinks wise, they advise against glass bottles for beer but you can get away with spirits.
