Quick little drawing of a fun little course. About as long as Singapore, so room to cut some.
I wanted to keep it to the center part of the Strip, so it includes all the important casinos (and mine, Bally's

) and runs by all the iconic sidewalk attractions like the Bellagio Fountains and such. I ran it through the back of the Strip a bit (East side) to cut through the Linq/High Roller (kind of like Vegas's Singapore Flyer or London Eye) parking lot. Where liberty was taken with the layout, since it is an empty parking lot after all.
Only thing I can't figure out is where to squeeze in the pit building, which I assume needs to be permanent, and around 300 meters long. I tried setting it in the Linq parking lot, but Linq road leading to Flamingo Road isn't wide enough to be a turn 1 corner.
Only other thing I can think of is really re-working that parking lot area by the Linq so the pit building can go there. There just isn't anywhere else on the route where a pit building can be built, there's no way considering the properties and real estate it cuts through. Guess I'll figure it out later, this is just draft 1. Be sure to zoom in and check out the detail, definitely wanted to be dynamic in some of the tighter corners.
In a perfect world, I'd love for the main grand stands to be opposite Lake Bellagio for an epic starting grid location.
