Downtown Hilton expansion to help area attract national events
Hoping to attract national political, sports and other events, officials expect to announce a plan soon to expand the existing Downtown Hilton.

The Dispatch has learned that officials are expected to announce in mid-March that the Hilton will be expanded across North High Street to abut the convention center and add 468 beds, giving it the 1,000 beds coveted by tourism officials. That proposal also would add an 18,000-square-foot ballroom and 42,000 square feet of meeting and conference rooms.
