Airport
This is the place that begins and ends the majority of people that show up at Vegas - and like the town, it is designed to take your money.
Firstly, and I find this interesting - why is it located right down the street from Las Vegas? To me, it seems they could have put it further away but on the other hand, it makes the time between getting your bags and getting out and gambling amazingly short.
Banks of slot machines everywhere - sort of has to be that way I guess - but they even put the damn things where you drop your rental cars just in case you had some spare change you didn't want to fly home with.
Big airport befitting a town that relies on chumps from all over - and in that respect, it gets the job done of moving hoardes of people in and out of town in a hurry.
Terminals were clean enough as were bathrooms - so at least that is a bonus.
The only game in town, so to speak, where you can know the outcome in advance!
