This airport is truly hit or miss.
I've been several times now and have always flown with different airlines so I've been fortunate to see most of the airport now.
Certain areas of the airport are barren where other areas are packed with food and stores and kiosks.
Luckily nothing is too far away so if you have a little bit of extra time you can walk over and get something to eat or find something to do.
Most of the airport has slots to gamble with but you'll never find any electronic table games (which I wish they had. No people required! But I understand there's probably some laws around that.)
If you smoke there are also enclosed areas within the airport to smoke and gamble, if that's your thing!
It's a big airport as well so you'll have to take a short train ride to where you have to pick up your luggage.
This area is well maintained and outside there are a bunch of options for shuttles or taxis to get for decent prices so you can pick and choose when you get there.
Overall it's a decent airport. There's just a lot of empty space.
As of November 2017 they seemed to be doing some construction so looks like they're trying to fill some of the empty space.
