I am going to Sumatra on a boat from Malaysia, next August. According to the Lonely Planet book, I will be asked to show I have enough money, on my way into Indonesia. Apparently, 2000 US dollars is the amount they find acceptable. I dont like the idea of taking out 2000 US dollars at a land border. An airport wouldnt be too threatening, but land borders generally have less security than airports, in my experience, and there often tend to be people hanging about selling things, and possibly some looking out for distracted travellers to rob. Maybe, I could show a couple of hundred dollars, instead of a couple of thousand? Has anyone gone from Malaysia to Sumatra on the boat? If so, what was you experience with proving you have enough money?
