Just got back from Vegas and rented from Sixt for a car rental. I thought I would share my story: We arrived late into Vegas as our flight was scheduled to land around 11:30PM on Saturday night. We took the bus to the Car Rental Center and got in line at the spot where the Sixt shuttle was supposed to pick us up. The security person said it should be here in a few minutes. We could see the Sixt building from there and we could see the bus parked with it's lights on for a while. Then, no lights. After 15 minutes or so, no shuttle. The Fox rental car center shuttle arrived twice in that amount of time. He asked why we were still there and when we told him (there were three groups of us), he offered to give us a ride to the gas station next door to the rental place. We agreed and thanked him (and tipped him) for his kindness. When we got to Sixt, there were two girls working alone. They informed us that they had no driver for the shuttle and apologized for not picking us up. They say they work on a skeleton crew at nights, etc etc. I was already pissed off at the time for not being picked up (when you call the number on the sign at the car rental center, it doesn't give you the option to connect to an actual person). I even downloaded the app as it was supposed to let you track the shuttle. Nothing. So as we now stood in line to get a car, we witnessed them not have a van as promised for the large group of 7 in front of us. They were going to give them a small car and have them come back tomorrow (because 7 people can safely fit into a 4 door sedan) but finally 'found' a large SUV that would work. We had rented a Mercedes and they 'upgraded' us to a BMW which I actually didn't like to drive as it had some nuances that took some getting used to. The bottom line is that the service was horrible as the two young ladies working were very overwhelmed and understaffed. I don't think I would ever rent from them again.
