Lets see what the terms say
If at least one night of the Member's stay is consumed with the use of HHonors Rewards Points, the entire stay is considered a "Reward Stay" and no HHonors Points may be earned, except that if Member is using Room Upgrade Rewards, any money spent on the original reservation will earn points and/or miles consistent with these Terms. Participating hotel will determine whether incidental charges incurred during either of those stays are eligible for points, except that Points will not be earned for incidental charges at Hampton Inn®, Hampton Inn & Suites®, Homewood Suites by Hilton®, and Home2 Suites by Hilton®.
