The timetable is wrong exactly when everybody wants to read it

An assistant is only as current as the last person who updated something

This is the honest limitation and it is worth stating in the product rather than discovering it on a holiday eve. If the club's hours live on a page nobody edited, the assistant will repeat that page accurately and uselessly. The fix is not cleverer software; it is one person owning one list of exception dates, and the assistant reading that list rather than the general timetable.

Exceptions are known months ahead, so they are not really exceptions

Holiday dates, eve-of-holiday shortened hours, the annual maintenance week, the pool's scheduled drain. Almost none of this is a surprise, and a club that writes a year of exception dates once has pre-answered its own highest-volume question. The work is an afternoon and it is the single highest-return administrative task in a club's calendar.

Partial closures are the ones that cause the wasted journey

"Open" and "everything is available" are different claims, and members read the first as the second. A gym open with the pool closed, classes cancelled but the floor open, reduced staffing with no induction available: each of those sends somebody home disappointed if the answer was a single word. State what is open, not whether the building is.

Say when the information was last confirmed

A date attached to the hours is worth more than the hours. A member who sees "holiday hours, confirmed on the fourth" knows how much to trust it and whether to check; a member who sees a bare timetable has no way to tell whether anybody looked. This is a small habit that converts a liability into a credible answer, and it costs one line.
