If you're a blue-level member that's correct. If you're Silver, Gold or Diamond there are bonus points calculated as a percentage on the 3000 base points.
Another question that comes up frequently - if you're watching points for elite qualification (in addition to stays or nights, it's possible to qualify on points), only the 3000 base points count toward elite qualification
Usually any incidental charges that go on your room, like bar, spa or restaurant tabs, also earn points.
It's difficult to qualify on points without reaching the stays or nights threshold first, but it's possible, for example if you entertain at the hotel and have a few $500 dinner tabs in addition to your nightly rate.
