I am wanting to surprise my wife with a limo for our upcoming Vegas trip. What is everybody's experience with Presidential's round trip airport service vs Bell-Trans ride share. I have seen where people say that Presidential will stop at The Welcome to Las Vegas sign, with Bell-Trans, they may not do that. Presidential would be about 80-90 dollars more. What about the condition of the cars? Is there any difference between what the two uses?Bell-Trans pictures look like older Lincolns, where as Presidential's cars look newer.
