if you hang with ballers like jason strasser like i did on my last trip to vegas, you circumvent this problem by taking limos

My late brother used to do the limo thang but mentioned that the expected tip to those guys was generally more than the corresponding taxi fare.

The real reason for using the hotel limo should be for (sense of) security.
