generate_three_hour_plan
ChatGPTResolve a written New York origin and return up to three complete 180-minute Manhattan plans with three curated stops, optional attributed historical and cultural context along the approximate route, an explicitly labelled self-directed period when needed, canonical IDs, published source links, freshness and limitations. Call at most once per user request: the successful result is authoritative, including its returned start time and any limitation on the origin-to-first-stop leg, and must not be retried merely to obtain another interpretation or map. For safe public park origins without a direct circuit, nearby_starts may return measured approaches instead of plans: ask the user to choose a reference and feasible time budget, and never set via silently. This read-only tool does not check live inventory, make reservations or guarantee live availability.
