Tourist attractions should add eyewear depth before known attendance peaks, especially sunglasses in outdoor environments, then return to a normal baseline afterward.
School holidays and tourism peaks
Use prior attendance and sell-through to plan temporary backstock.
Weather

Special events
Event-specific traffic can justify more inventory at selected retail points without changing every location.
Protect readers
Keep useful powers for maps, menus, phones, tickets, and programs regardless of sun season.
