My biological sister and I have had NUMEROUS house parties and have NEVER, EVER had a single problem. This past weekend we had a bash and about 1:30am I get a call from my neighbor asking that we keep it down b/c we woke him up. There were only about 10 people outside but I had them come inside. My street is a cul-de-sac with only about 15 houses on the street, so you can imagine that with about 40 people at my house that night, there was lots of traffic down a generally quiet street. The next day my neighbor told my dad that after he called and spoke with me at 1:30, we continued to be loud, we had blaring music, and that we had vehicles up and down the street until 5 in the morning. It was a very low-key get-together, but supposedly my neighbor couldn't sleep. He never bothered to call my house again and let me know, although I know we weren't loud after his call. This neighbor that was complaining lives across the street from me. NONE of my other neighbors complained what-so-ever, not even the next door neighbors who always complain about my dog keeping them awake all night b/c of her non-stop barking.
Here's the deal:
In a few weeks my sister and I are having another party and are expecting it to be about twice the size as the one we had this past weekend. In order to keep things as quiet as possible, I won't allow anybody to be standing in front of the house. If they want to smoke or get a fresh breath of air, they can go to the back yard, but I do not want anybody "hanging out" in the back yard. Other than that, I have no other ideas as to how we can keep the party "under control." Like I mentioned, we've never had any problems before, but with my neighbor acting silly this past weekend, I think I need to take certain precautions for our next bash. My sister told his daughter about our upcoming bash, but I am not sure if her dad (the complainant) knows about it. If I were to talk to him about the bash beforehand and ask him to call me if there were any problems, I know he would call and expect me to send everyone home, which I will not do (not immediately, any way). What is good common ground for this situation? Should I ask people to carpool? Not to be leaving and coming back? Our parties are always a blast and I don't want to put a damper on our infamous Mardi Gras party because of a silly neighbor.
Okay, I think I covered what was important. I need some major help with this situation, as I've never been in this situation before. Thanks in advance to all of you party animals who know the ropes and want to help a girl out.

I'd also be interested in hearing from people who are on the other side of the table and have been bothered by partying neighbors. Thank ya much!
