Fox is a good deal in LAS. You have to take the main shuttle anyway to the rental car terminal in Las Vegas for any car rental. From there you get on the fox shuttle that takes you off terminal about a 7 minute ride. If you don't have 7 - 10 minutes to spare then you should not be renting a car in the first place let alone be flying. The Fox experience is no different than  any other rental car experience. Some times you win.... some times you lose....  what a bunch of whiners!!
