LAS is close to the Strip, which makes it tempting. That closeness is useful, but rideshare pickup, resort walking distances, and security return still matter.
What to do with bags
If you cannot check your bag with the airline, consider whether your destination can hold it. Many resort bell desks only store bags for guests, so verify before leaving the terminal.
Leaving the airport
A single nearby resort, meal, or short Strip walk is the right scale. Do not build a casino crawl unless missing the flight would be funny to future you.
Getting back through security
Return earlier at night and during event weekends. LAS can swing from easy to crowded quickly.
