We are heading to the border of Mexico in a rental van loaded with things for our house..after dropping teh van off......we are meeting a driver in Laredo who will pick us up and drive us into Mexico and our final destination....and the dilemma is that we want to use Priority Points all the way down to stay at the hotels so we limit the $$.... therefore we need to sort of plan our daily driving allotment so that we can get to our next night's reservation.....not ideal...but when the money is tight it is an option.....
