Hi Devin
You have an enormous challenge with your site, because you don't fit into a niche, and that leaves you competing against a slew of larger, better funded travel-related sites. You have some great content, written by a few good writers and a slew of decent writers, but that's not enough to break through your plateau and hit the big leagues. And to be honest, while you have a great site, I really can't tell what your goal is with it, what your market is.
Think first about these questions: Who is your site for? What audience are you trying to reach? Who are you trying to compete against? Is your goal to sell travel, or just to tell stories?
If you're trying to reach people looking for destination reviews, then you're competing against TripAdvisor, Yahoo Travel, AOL Travel, and several other already well-branded review sites.
If you're trying to reach people looking for general travel literature, then you're competing against MatadorNetwork, BootsnAll, WorldHum, and countless others who offer either great literature (WorldHum), great adventure (BootsnAll), or a great community (Matador).
If you're trying to reach people looking to book travel, then you're competing against Travelocity, Expedia, Orbitz, Kayak, Hotwire, Hotels.com, etc.
All of those sites are some pretty stiff competition.
I really think what you need to do is first determine where you want to position ITKT, what target audience you're trying most to reach (your market), and then model yourself after the competition in that market, with the goal of either doing better than they are, or doing as well as you possibly can to stay in that pack.
Also, once it's clear exactly where you want to fit in, then I think you'll be able to get better advice on how to continue to grow.
