> That's why they use Google Docs or Word or Google Sheets True, planning content itself is already annoying. I had an idea on UX, it needs to be as easy as using Spreadsheet cells but better visualization (a simple cute linked list like metro train chart maybe). Pick those common columns and visualize it nicely. Try not to complicate it more. > Monetization with affiliates is OK I personally do not like any form of ads, so it's bad for me. I was thinking about selling this data organizing to travel agencies, they already have all content. Let them create nicer packages (easier to understand itinerary). Maybe they can sell that for people who want to go by themselves. $3 per itinerary (can export to pdf, make it pretty when printed, so no needs phone battery all the time) - Acquiring users is hard since users don't travel often, and the typical channels for infrequently-used product growth This is uncertain, I'm not really sure it's problem. Actually I don't think it will be a problem but fear it would I think you already did an intensive analysis so good luck!
