At the LV airport I stopped at a shuttle service for $8. They weren't very friendly and gave me one word answers to my questions. There was a 20 min wait. I walked down and stopped at Super Shuttle for $11. Super friendly! 15 minute wait. They did everything for me. The bus/van they had was sooo comfortable. They dropped me off at the Luxor first. I guess that's their first stop so I got lucky! The driver was awesome. Then I made an appointment to pick me up at the end of the trip. I was nervous because I didn't have much time til my flight left. They were not worried. They know what they are doing, you just have to trust that! The driver actually showed up early too...who does that?!? :-) I will definitely use Super Shuttle whenever it's an option.
