An itinerary app could turn a traveller's dates, interests and practical constraints into an organised plan. It must distinguish suggested activities from confirmed reservations and account for realistic travel time between locations.
Users need to edit recommendations and see where information came from. Opening times and availability can change, so important details should be confirmed with the provider. Private travel documents require different storage and sharing controls from a general wish list.
Pilot one destination or trip type and test a closed attraction, bad weather and a changed arrival time. Avoid promising a perfect automatically generated holiday. The useful product is an adjustable plan that clearly shows what is proposed, what is booked and what still needs checking.
