This can be a quick way to double the 500 miles from Points & Miles to earn 1,000 miles per hotel stay.
Hampton Inn and Homewood Suites only earn 100 miles per stay regularly so this promotion takes that to 200 miles.
Big spenders can set earning preference to Points and Fixed Miles to earn 1 mile per $1 and double that to 2 miles per $1 during this promotion. This is probably a better deal if staying at Hampton Inn or Homewood Suites with more than $100 in charges or spending more than $500 per stay at another Hilton brand.
