Fuller's Index uses the address "3145 Las Vegas Blvd South" for Wagon Wheel / The Players. This is actually the address for Desert Inn used after "Las Vegas Blvd" was established in 1959, and we don't know exactly where small Wagon Wheel was on the large Desert Inn property. Here's a photo circa 1947 showing the foundation of Desert Inn. There's small building in the area, but it's not clear whether they are The Players, El Toro, or another.
