Last weekend was Clemson homecoming. At the last minute I decided to check and see how close I could get a room. I was traveling with a Silver member and he could only find rewards over 30 miles away, but I was able to pick up a special diamond only award night at the Hampton Inn in Clemson.
Another friend who is a Marriott Platinum was stuck staying at a Jameson Inn 10 miles away for $$ since she couldn’t use her points as close as she wanted to be on points.
This is just one data point, but still Hilton has treated me well.
