Hilton categorizes its properties into ten groups. A night in a Category 1 hotel requires 5000 points, a night in a Category 10 hotel requires 70,000 to 95,000 points.
Here is an interactive map that shows you just the Cat 1 or Cat 2 properties, or all of Hilton’s properties.
Double-click anywhere on the map to zoom in. Drag your mouse to scroll around. I haven’t figured out how to zoom out.
