when dealing through Priceline, you're best off assuming you get -nothing- other than a basic room(often the 'Priceline room', with views of garages, brick walls, etc).

Anything on top of that is a plus.

Extraneous points, such as for incidentals, seem to be hit or miss. Read up on that one for more info.
If you're after elite status, be sure and monitor 'stay credit' vs. no credit for PL.

All that said, PL can often worth putting up with. Before they went snobbish, I used to book the Tahoe Hyatt through PL for great rates, during off season.
I still love the resort, but it just costs more, now.
