Observing over the decades, ACA has always evolved with the times. If a trip sold out early one year, they'd add additional date(s) the next. If sign-up was light, the trip could and often did get dropped from the organization's offerings.

In addition, the current management is focusing on the 'untoured', evangelizing to the touring curious and potential first-timers. They've started a big short tours and overnighters initiative and are funding under-represented demographic groups.
