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.
