Aruba towns

I always thought that Oranjestad is the only place that we could visit in Aruba. They say the island has so many towns too. If you have been to Aruba, what towns have you visited?

I haven't gone to Aruba yet. I know one and it's called Savaneta. I have read this is one of the oldest town in the island. Do you think there would be lots of towns in the island? I mean, Aruba is not quite a huge place and I doubt if we could visit lots of towns.
