Americans are expected to take to the roads in record numbers on the Memorial Day holiday weekend. Triple-A is expecting nearly 37 million people to travel at least 50 miles away from home. That represents an increase of more than three and a half percent over last year's numbers. About 31 million of those travelers will be heading out by motor vehicle while nearly two million will travel by train, and more than four million will fly. Despite record high gas prices, the Travel Industry Association is predicting people will make 334 million trips of 50 miles or more. TIA's Suzanne Cook says summer travel will start off with a bang Memorial Day weekend and continue strong through August. She predicts hotel occupancy will rise about four percent and room rates will increase by about two percent.
