Prompt
I'm organizing a 3-day sightseeing trip to Tokyo across Shibuya, Asakusa, and Tsukiji Outer Market. Can you map out a balanced schedule that factors in transit times between attractions, sets aside windows for dining reservations, builds in buffer periods for casual wandering, and suggests backup plans? Please format this as a structured travel plan complete with a timestamp header, detailed results, and a section for actionable next steps.
