Sometimes it means a genuinely serene resort. Sometimes it means a party hotel with an age limit. The label alone tells you less than people assume.
The term guarantees an age policy, nothing more.
An adults-only resort in Ayia Napa and an adults-only resort in Mauritius are aiming at completely different people. What you actually want to know is the atmosphere: whether there's entertainment until midnight, whether the pool has a DJ, and whether it's couples or groups. We check that rather than trusting the label — and if you want quiet, an adults *wing* of a family resort is often calmer than a standalone adults-only hotel with a party reputation.
