Marsya, your total seems to be closest to what I was expecting, for two.
$1,250 for hotels (Tues - Monday)
$75 for parking
$600 for meals (breakfast is included in the price of the room at our hotel)
$ 400 Events / Badges
$150 Gas
$500 Dealer Hall
$150 outside sightseeing (King Tut Exhibit)
Of course, we then have to pay exchange - it's been anywhere from 8% to 20% over the last few months...
