First time in Vegas this July for my wife and me. We are arriving late on a Monday evening (about 10:30 p.m.) and going to the Signature at MGM Grand. Not partial to shuttles, so thinking of taking a cab. I have two questions for someone... 1.What is the most direct cab route from McCarran to our hotel at that time of night (street names)? 2.Should I just forego the cab and take a towncar? Thanks for the help!
