I'm thinking about building an app that takes a users origin and destination [Detroit to Denver] and dates [13 through 19 June] Based on this data, I wish to build an itinerary for users, places that can be explored, based on those places recommended hotels, flights and rentals can be automatically booked. This is a complex idea. I'm wondering if users would trust an app to make all the decisions for them.
