Before I build the detailed day‑by‑day plan I need your conference start date, whether the ATTEM conference is in Mexico City (please confirm city), preferred departure date/time, and whether you prefer Mumbai or Pune for international flights. This ensures accurate flight options, hotel booking windows and local recommendations.
Tell me your budget (economy/business), hotel preferences (location near conference centre or city centre), and any dietary/allergy needs so I can recommend specific restaurants and logistics.
