You are correct abotu the waterfall thingy...If I am correct it is the location of the map that I had posted....what gave me teh clue about four queens was the outer part of the building surface in teh top right of the picture that splashbar posted. I knew that was four queens from staying there and also taking a picture up teh side of the building

and the map I posted before photo

I also would dontate the chip too....it was a great game
