Weather disruption does not have to kill city itineraries. The key is to design alternatives in the same neighborhood and time window before the trip starts.
Build Layer A and Layer B
Layer A is your ideal plan. Layer B keeps similar theme and timing but swaps exposure type, such as replacing skyline viewpoints with museums or covered markets.
Keep Geography Constant
Fallbacks should avoid long re-routing. If rain begins, you should pivot within walking distance rather than rebuild the day across the city.
Planning Reliability
Alfred can pre-map weather contingencies by district so sudden changes feel like controlled pivots, not emergency replans.
