Yes I did that when I was in the USA on business but the first company that I had pre-booked from the UK failed to come up with the goods and then the next company that I booked did the same thing!
Time was getting tight by the time I found company number three, they did a great job but at about 30% above the costs that the adverts in the UK flying raggs stated.
May be I was unlucky but the USA is not always as good as some would have us think.
