First of all, everyone involved should take a break from smoking before the date of the party, to drop their built-up tolerance.

Second of all, don't do it in a hotel. It may seem like the only thing you can do, but it simply isn't. You don't have to do this now. Wait til an opportunity comes up for you to use a house. It will come eventually.

When you're high, you forget about the world outside of the room you're in. Therefore even if you're planning on keeping quiet, once you all start smoking, that will be over. Noise complaints, knock on door, busted.

And that's assuming the accumulated scent of smoke from eight ounces of pot doesn't get you busted by itself.

Hell, on second thought, do this:

Have a field party. We used to have them all the time. Drive somewhere out of town, to a road completely isolated that NEVER has a single car on it. From there, drive into a field and keep driving until you can no longer see the road. (Or any other indication of civilization, for that matter.) Either set up camp or bring enough vehicles for everybody to have a place to sleep.

We'd set up a lounge by bringing two truck, dropping both tailgates, and backing them up extremely close to one another. This can make a comfortable lounge for about 14 people.

This also really enhances the experience of getting high. You're in the middle of no where. Sure, when you're high you usually THINK there's no outside world, but for a change there truly isn't.

Plus, the nearby road serves as a safe(er) means of driving for those who simply love to drive when high. Especially those who like intentionally getting lost just for the adventure of finding the way back. Bring a few people though, its hard to find our way back by yourself.

If you see headlights at any distance away, don't wait to make sure they're heading your way. Leave, right then. Choose a place with at least ways of exiting, as well.
