It's been 3 years since I've stayed there regularly, but the HR is nicer than HP. They're only about 2 or 3 blocks away from each other; I used to bounce between two in order to get more stay credits. The price difference wasn't very much between the two at the time. I would pay a few extra dollars to stay at HR.
I found the sandwich and beers that they gave you at the HR as the welcome amenity more valuable than the points if you're hungry for a meal.
They are not located in the best part of town; that gives HR an extra edge because it has better facilities.
Very convenient to the airport and both had free airport shuttles.
