The mall diagonally opposite your hotel (opposite Lot 10 shopping complex) (Sungei something)has a cruising "floor" - find the Reliance Travel Agency on (I think) the 3rd floor - the cruising's not far away (just keep your eyes open, you'll soon realise who's around and what's going on) although it pays not to be self-conscious (all the shopkeepers know that's what you're there for). Lot 10 also has possibilities and there's an overpass between the two buildings. I'd be trying the
