They make it very easy to get into Vegas. I go about once a year and when I get to baggage claim, most of the claims are not being used as I guess the flight arrivals are spread out.
Once you go outside, it's very easy to got a taxi or a shuttle.
Sadly when leaving the security line is just nuts. Make sure to arrive 2 hours prior to your flight departure.
If you are flying Southwest, your eating options are limited to fast food.
