The BOS staff are pretty great. (Odds of all this working are much lower if you don't rent the room... you're not even supposed to have outside food.)

Someone unthread said “unless you are shouting,” well I’m not sure you will be able to avoid shouting under those circumstances (and if you do avoid shouting it doesn’t seem like much of a celebration).
