The quiet hour at the pool may be what lets someone participate at all.

Quiet sessions are not a small courtesy at the edge of a timetable. For somebody who needs more room, more time, less noise or fewer eyes, that hour is the difference between swimming and not swimming. From outside it can look like an empty pool that could be used more efficiently. From inside it is the only version of the place that works. Access is often a question of when.

If you help decide how a space or a schedule is used, look at who comes during the quiet parts before trimming them. If you use somewhere at busy times, notice how much of it assumes a body like yours.
