It appears that higher gasoline prices will not keep U.S. travelers off the road over the Fourth of July holiday weekend. AAA projects that, overall, 41-million motorists and other American travelers will spend holiday time fifty or more miles from home over the weekend. That is an increase of nearly two percent over last year’s Fourth of July numbers. This comes even with gasoline prices at their highest levels for this time of the year since 2008. As is usually the case, this weekend will be the busiest of the summer for domestic travel. And some booking agencies are seeing more than half of their customers’ travel destinations being outside the country Airfares and hotel rates are also expected to be at their highest levels of the summer this weekend.
