Ask for party size and write it into reservation-creation state.
When to use: Classic occupancy booking where headcount drives plan-element capacity, quotas, or position quantities.
Typical place in the funnel: Near the start — often right before or after a time-frame step, then Selezione manuale del posto a sedere (ManualSelectPlanElements) / Seleziona automaticamente gli elementi del piano (AutoSelectPlanElements).
Outputs: Selected person count (and related reservation-creation parameters) used by selection, quota, and pricing steps.
Alternatives: Numero di persone tramite parametri (PersonCountFromParameters) when counts are already collected as custom inputs; Modulo di input (RequireInput) for age-band or ticket-type counters that are not the main party-size field.
