Planning a trip to Las Vegas? Most likely, you won’t see Las Vegas at all. You will land at the airport in Paradise NV, and you might be staying at Circus Circus in Winchester NV. These two places are actually “unincorporated towns” and don’t appear in postal addresses (“Las Vegas” and the zip code is sufficient city info for these places)
If you’re at the Strat(osphere) Tower or “downtown”, you’re in Las Vegas.
You can view the city limits of Vegas via this Google Maps link. As you can see, the intersection of Las Vegas Blvd. (the Strip) and Sahara Ave. is the southern border of the city - the rest of the Strip below that is in unincorporated Clark County. That’s by design - the mob bosses and other entrepreneurs who opened the earliest resorts on the Strip did so to evade regulations present on Fremont St., a few miles to the north, the historical portion of which is entirely within city limits.
Personally, I’m intrigued by some of the tiny enclaves northwest of the touristy part of town, in some of which it looks like there are individual properties that have never been annexed into the city.
I had a 1 hour layover in Vegas once a long time ago. The airport is basically just another casino, but with planes!
I only had a couple of dollars on me and I really only had time to do one of two things: stick my two bucks in a slot machine, or get a couple of tacos at Taco Bell (it was right next to my connecting gate). There was really no winning choice there. I went with the Taco Bell.
