Hilton is announcing some big changes to the Hilton Honors program. Starting March 28, 2013 the loyalty program will jump to ten hotel reward categories. Hilton's e-mail to HHonors members claims the change is to accommodate the growing numnber of hotels and resorts in the Hilton family. There are currently seven award categories. Reward categories determine how many HHonors points a member will earn for a stay as well as how many points are necessary for a free night. The higher the category, the more points required.
