I came across this today and thought that it might be helpful for some people. Google now offers the maps of the first floor of just about all the casinos on the strip. They also show elevator locations, bathrooms, etc... I can see it being pretty neat for first time visitors to the city who have a smartphone with GPS. To see the floor maps, just go to Google maps and find your favorite casino and just keep zooming in on the maps until you can see the floor map. This has to be done in Map View, Satellite view will not show the floor maps. The only downside is that currently it's only Strip properties, and it only shows the first floor.
