Slot machines are posted throughout the airport after security and billboards for shows, restaurants, venus are played on screens etc. There is Terminal 1, or 3. For some reason they skipped 2?? They have like 50+ restaurants between each terminal. There is free wifi and the airport is very clean from what I've seen.
Uber/Lyft in terminal 1 is on parking floor 2M. For some stupid reason they have signs that say "Ride Sharing" instead of just promoting the service name. It's a sore spot for vegas... If you rented a car the location of most of the car rental places aren't actually in the airport. Its about a 1-2 mile drive from the airport but most rental places offer a shuttle. I don't recommend taking a cab. 4-5 in my experience are incompetent and don't know what they are doing and drive while using the phone.
The airport itself is easy to maneuver and easy to find where you need to go. The tram only takes about 4-5 minutes if you need to go to the D gates. This is a very enjoyable airport.
