When we host house parties they are always byob. We provide several ice chests for the storage of beer etc, ice for mixed drinks, we usually have on hand a few standard sodas etc for mixers but most people bring their own mixers anyhow. Disposable cups for mixed drinks comes in handy and we put out perm markers by the cups for people to write their names on cups so they dont misplace them while partying. Later in the evening we go thru several pots of coffee for those who want it. Theres always bottled water in the house, but most that want it bring their own.
On the invites we always specify for all to bring their own condoms! Everyone prefers a different brand it seems...no way you can stock for them all! We put a bottle of lube or two in each play area of the house along with a box of baby wipes, towels for the squirters and always make sure there is a trash can in each room/play area too. We usually have an assortment of condoms should someone forget theirs or not bring enough.
in the bathrooms we put piles of wash cloths, hand towels and full sized towels on the counter. This way people dont have to dig thru the linen closest looking for these items. Also make sure to have plenty of toilet paper LOL, nothing worse than running out of that at a party!!!
Extra sheets is a must at our parties! Seems the beds always get well used and need to be changed during the course of the evening!
As far as food....we provide munchies...chips, dips, veggie tray, fruit tray, something sweet like cookies. The people at our parties are there to play not to eat a meal so we usually have lots of munchies left over
