Meanwhile, Fujifilm thrived post-film by recognizing they're really in the chemical business, and pivoted well (to pharmaceuticals, cosmetics, and highly functional materials).
Since drinking coffee is also a main cause of teeth-yellowing; if this substitutes coffee, then it could also be seen as another way of helping to keep teeth whiter?
I don't think offering more information, or charging less, would solve your problem. If I had wanted more information, I'd buy a guidebook. As SHOwnsYou mentioned, it's about having (good) itinerary decisions made for me. The value isn't in the amount of information, but the judgment that went into filtering and digesting the over-info out there in other travel sites/books.
To complement that value, your design needs to give a sense of 'here's the distilled gem about this city' - it should just 'hit me'. Instead, I am presented instead with a rather drab plain page, which feels like it'd take forever to get through to gratification.
I'd echo suggestions to look into redesigning the page to make the visual impact, fast.
