A lot of people report receiving HHonors privileges w/PL bookings. However, PL and other similar bookings do not earn miles, points, etc....

The HHonors TCs state:

Eligible Rate stays are stays at all rates except wholesale/tour operator packages, contracted airline crew rates, complimentary or barter rooms, stays on NET Group, Series Group or IT Group rates, contracted Entertainment or Encore rates and stays using airline percent-off award certificates. Stays that are booked via third party websites are not Eligible Stays irrespective of rate paid, for the purpose of earning points, miles or stay credit toward VIP tier status. Stays booked via "opaque" channels where the brand is unknown at the time of purchase are not Eligible Stays for the purpose of earning points, miles or stay credit toward VIP tier status, or the receipt of VIP tier benefits such as upgraded accommodations / amenities or access to health clubs.
