I started a new game in Barnacle Bay and placed my Sim Piglet Snout in her high rise apartment. Using Edit Town, I placed some (not all) of the Late Night clubs. I used the World Editor to make new lots that were big enough for the buildings. At first, I didn't think it was going to work because, while there's plenty of empty space in Barnacle Bay, it's not flat. All of the buildings had the sharp, steep edges and I didn't think Piglet would be able to get in. I was wrong, though, because she did! She's been into 3 clubs so far with no trouble at all, even though they have the sharp edges. They don't look good because of it, but they are functioning properly.
I'll keep playing it for awhile and give you an update, Pally, but I wanted to give you the initial results while you're still online.
Edited to add: I've also discovered that almost everyone is a celebrity right at the start of the game. I've seen celebrities up to 3 stars just by going to the bookstore. Seriously, at least 75% of the regular townies I encountered on the first day were celebrities. No vampires yet, though.
