Rooms or the resort proper? Two totally different questions.
As far as the rooms go, I don't know that I ever remember seeing what I would call traditional "partying" anywhere.
As far as a bustling and active restaurant, lobby, and bar areas, I think you'd have to look pretty hard to top Jambo House on a happnin' night. OKW outside area is probably a close second, but Gurgling is so small that it prevents it from rising to what I would call a "partying" level. Damn good time there though. Tends to be a late afternoon/early evening thing there more so than late night really in my experiences. No other
DVC really rises to the level of either one of these in my experience.
Edit to add: BWV used to be busy at night. In a good way. But when they removed the live entertainment, they virtually killed it. ESPN not opening back up yet isn't helping either at this point. #MissedOpportunities
