1. I love that I got off the plane and there was a large vending machine with rose bouquets inside. Only place I've ever seen that. It reminds me of the crazy vending machines in Japan where you can find almost anything except maybe roses!
2. Slot machines everywhere!
3. Don't take the mass transit to the strip. Take a cab. You aren't saving much by taking the buses. Also, if you are there with other people, you save money by taking a cab. The line for the bus can be crazy long!
4. The line to go through security changes length all the time. Sometimes you can rush straight through, but most of the time it's LONG.
