From Bukit Lawang we went to the airport of Sumatra and took a flight to Jakarta. We just came out of the airport when we see the Ibis shuttle bus slipping away. And believe me we waited to hours in the dark for the next one. Finally it arrived and we had a good sleep. Next day we flew to the awesome Singapore airport and there was a connection tree IMAGES where you could play video games against people who were at the tree. Then we flew to Colombo ( Sri Lanka ) and waited another hour for our taxi to arrive and collect us at 2 o'clock in the morning! We didn't do much in the hotel apart from playing in the pool. Next day we took the train to the city which was -hundreds of years ago- the biggest city in the world.
