Anyone that cares has probably already seen it in my PSN post. But here's a new way to get into those hidden interiors.
INT-Funhouse
Arrows point to entry points for each hidden location.

*Police Line-up Rooms
*Police Mugshot Rooms
*Comedy Club
*Winner's Celebration Parking Lot
*Low End Apartment
*Motel Room
I found that the mid and high-end apartments were no longer there, neither was the 10 car garage. I think they got removed because of griefers. Either way, we have easy entry to them now. A reliable way in which everyone can get in. And to get out, all you do is hold triangle to respawn back to the last checkpoint. It's a GTA stunt race obviously, so you can walk around and leave your bikes alone.
I was hoping to make use of the comedy club bar area instead of the stage area for rockabilly & possibly biker theme nights.
