Tutuala's a great spot. In '98, when I signed in to the guest house there (the only place to stay), nobody had signed in for almost four months! But it wasn't anywhere close to as big as Baucau or Aileu, for example. Maybe a thousand people. If I had to guess, I'd say closer to 300. I can't even imagine what you could possibly combine Tutuala with to create a bigger "metro" population.
