ON LOCATION: Hilton Boston Logan Airport

The Hilton Boston Logan Airport, with 600 guest rooms--and space to expand by another 300 rooms--recently opened, almost three months ahead of schedule. The $100 million hotel offers a quiet respite (No, I really mean it!) in the middle of the seventh-busiest international gateway to the United States. All guest rooms have extra-large windows with soundproof glass and casings, bringing the spectacular views of Boston's skyline, harbor, and airport inside while leaving the noise outside. Rooms
