Free Night Certificates are one of the few parts of hotel programs that still create real value, but only when they’re applied to the right stay.
Across Marriott, Hilton, and IHG, the rules look similar on paper. In practice, caps, top-ups, and availability shape what you can actually book.
This page pulls together how they’re used, where they work, and where they don’t.

Closing
Free Night Certificates only make sense in the context of a stay you already want to book.
Used well, they reduce the cost of that stay. Used poorly, they push you into the wrong one.
That distinction runs through everything here.
