Where should AI stop and the human take over in trip planning?

I've been thinking about this a lot lately. Planning a trip used to mean hours (sometimes days) of YouTube vlogs, Reddit threads, and blog posts, piecing together a day-by-day plan from a dozen different sources. Some people genuinely love that process. Others just want to get to the good part: the trip itself. I'm one of the people who love creating travel itineraries.

One question has been sitting in the back of my mind while building a travel planner app: what part of trip planning do people actually enjoy?

When I ask friends why they love planning a trip, almost nobody says it's because they enjoy comparing exchange rates, checking opening hours, figuring out which neighborhoods make sense geographically, or discovering that a restaurant they saved closed three years ago.

What they enjoy is imagining themselves there. Finding the café they'd happily spend an afternoon in. Discovering a neighborhood they hadn't heard of. Choosing between hiking through a national park or wandering local markets. The excitement comes from the possibilities — not from the logistics.

That distinction has changed the way I think about AI in travel. Rather than replacing the planning process, I think AI is most valuable when it quietly handles the repetitive work in the background:

• Organizing days geographically instead of zigzagging across a city
• Checking whether attractions are actually open
• Factoring in weather, budgets, transit times, and local events
• Suggesting alternatives when plans change

The human still decides what kind of trip they want. AI simply makes it easier to build that trip.

Of course, there are risks. If every itinerary comes from the same prompt, every traveler starts seeing the same restaurants, the same viewpoints, and the same "hidden gems." That's not discovery — it's another algorithmic feed.

I've been experimenting with ways to avoid that by grounding recommendations in real places and encouraging neighborhood-level exploration instead of checklist tourism. It's made me realize the hardest part isn't generating an itinerary — it's preserving the feeling that you're discovering a place rather than having it dictated to you.

I've been testing this with a small app I'm building on the side (Routinex.Travel) using my own family trips, and it's made me curious where other people land.

Does having an AI generate the framework free you up to focus on the parts you actually care about — flights, hotel, that one restaurant you've been wanting to try? Or does it strip out something valuable about the planning process itself?

So I'm curious how others in the travel industry see it, especially those of you closer to the content/creator side. As AI becomes a bigger part of travel planning, where do you think the line is? What parts of planning should always remain human, and what parts are you happy to hand over to AI?
