Call all your friends, or just invite up some random people, and every time things get loud, start screaming filthy things at the wall. Profuse banging is encouraged. Then, while exiting your room for more con fun, \they'll\ be the ones staring at /you/ uncomfortably.
hahahah i so understand in the last vacation I stayed at a very cheap motel because it was holiday season and almost nothing is with vacant unless it is very expensive, and like we occupied almost the room just to left bags, but the neighbors were so noisy who at 2 o'clock in the morning almost all days they were put to their business (you know what I mean) like possessed, god! was so disturbing xD
I can say I know what you mean... This happened to me last year when I got down to Marseilles (Im in France) to the "JapanExpo" South. I slept in a hotel for 2 nights and I could hear some couples "having fun" in the room next to mine. >~<

NOT what you need when you've gotta get up early for a con!! jeeze.. - we were in one room in Birmingham once where the neighbours were pulling some freaky animal noise shit!! - I KID YOU NOT! Horses, in particular it seemed.. - we ended up joining in from our room and laughing so much that I think we put them off!!
