I like this airport for my layovers than other airports as you can preoccupy yourself with the slot machine or the bars. It is Vegas. I wonder though if anyone actually wins. Each terminal is pretty small compared to other airports' terminals, which makes it easy to walk around without getting too tired or without being late for your connection flight. They have a few charging stations and of course Ethel M chocolates!
The airport appears old. Since it's also smaller, there are not a lot of seats and the seats are uncomfortable, so it sucks when you fly in or out of here. It can get crowded and claustrophobic quick, so it's almost better to go to the bars/restaurants. I always see people sitting on the ground bc there are not enough seats. As mentioned by others, the taxi line can be long. I think that's a given anywhere. I suggest calling a shuttle company. Shared shuttles are cheaper too and you can get a discount if you schedule a roundtrip vs one way.
