Component

Derive party size from parameters already collected (usually custom integer inputs) instead of a dedicated person-count UI.

When to use: Tile or Formulaire de saisie (RequireInput) flows that ask “adults / children” as separate fields, then need a single person-count for occupancy.

Typical place in the funnel: After Formulaire de saisie (RequireInput) or Sélection des tuiles (TileSelectionInput), before Utiliser des quotas (UseQuotas) / plan-element selection / Ajouter une position (AddPositionToOrder).

See Saisie du nombre de personnes (PersonCountInput) and pattern booking-classic-occupancy.
