How to hold a party at the park

There is spooky party? Man, I haven't played in a while. I do love playing party animal sims though. What I did in my game to make partying easy: Step 1; Make a household of a bunch of dudes, who would be my party buddies. Step 2: move them in with the Landgraabs. Step 3: Delete the Landgraabs, while keeping all their money. Ka-ching! Step 4: Build them a new big home with the free money, equip it with all the party essentials. Step 5: Head over to greet your new neighbors. Step 6: Throw a party and invite your party buddies to their own home.

It's great for the sims who are new to the neighborhood and can't afford all those bars and stereos themselves. You could, of course, keep the Landgraabs, but I feel they're too stiff to be my party buddies. And I think their house was lacking some party stuff too.

Maybe you can save the rooms of your desert park lot and then remake it on another lot and move someone in there?
