I would like to contribute my story also to learn for others. I was traveling with my son of 16 years old and I'm an experienced traelller. When we arrived in Delhi last Sunday night it was 02:00 am. We went outside the airport and immediately we had some people behind us for taxis. We went straight to the taxi booth outside and booked a taxi to Paharganj area where we already had a prebooked hotel. One guy showed us the way to the taxi. He didn't take a taxi Faridah was already standing there, which alerts me a bit and than he joined the driver! Another alert. But honestly I was tired and went along as it seemed official with the note from the booth. In the taxi the guy from the booth starts talking about festivals etc. another alert. When we arrived in the area of Paharganj we arrived at blocked streets and I insisted that he would bring me to the hotel anyhow. But he drove us to an official office which could help us with different hotel, which I kindly refused. Than he wanted us to sell train tickets but I told him I bought them already via clear trip. He wanted to see the tickets but I refused. Then he said the only way to get in is by rickshaw. I didn't agree but according to him there was no other way. I got a bit upset to guy from the booth and then we drove away. But we were brought to a rickshaw driver and he could drive us into the area. Before I realized the taxi driver took off with booth guy and we were left alone in the darkness of Delhi with a rickshaw driver who only spoke a few words,of of English. Mind it was already 03:00 am in the morning and we had a 8 hour flight from Amsterdam behind us, so we were exhausted and they knew. The rickshaw driver brought us to the area again and again we were blocked. A guy appeared and he said that due to the festival the whole area was blocked and that it was dangerous to go out on the street in Delhi because of robbers and so on. The rickshaw driver wanted to have a stop there but I threatened him to drive onwards tot the lighted streets again. I told him to drive us to any other hotel. But he said he couldn't help us in his few words of English. He drove us to another official tourist office where e man waited happy to help us. I told him very agitated that I don't want any help or hotel or train ticket but someone to bring me to the prebooked hotel. Of course he couldn't help because of the roadblocks. I said no problem and took my telephone and said I call the police, please give me the address. Then he got agitated and said I had to leave immediately. I told him that I wiould not and would stay in the office till the morning. I said I would not and otherwise would hang outside. I realized only later that this was not what he wanted because more scams were going on at the same time and he didn't want us to meet others. In fact we saw at least 2 other rickshaws with tourists driving to the same road blocks. So this guy from the tourist office went outside with me and immediately called for a rickshaw driver in the area. This guy again tried to bring us to the closed area. I told him not to do so an stop it and bring us to a hotel. He asked the budget and I said 1000 rupees or so. Of course this wasn't possible and he tried to convince us that the price was much higher. I told him that he should just bring us to a hotel and stop the hassling. We were brought to a cheaper hotel..When we entered the hotel was surprised and that relaxed me. We were now in a hotel and they seemed not part of the scam otherwise they would have been awake! They offered me a room from the standard rate and I negotiated it down to 2000 rupees. Which is a shame but at least not too much. I knew that we were close to the original hotel but all I wanted now was safety! Next morning I found out that our original hotel was only 5 minutes drive from here and there were only a few blocked roads in the area. Everything could be reached! I think in hindsight we were lucky! The experience only costed us a good night of sleep and 2000 rupees.
My advice: when one arrives in Delhi airport go to a taxi booth inside, not outside. Beter inside so you can quitely talk with them. This is impossible outside! Take care of the exchange scam mentioned in other stories! Ask for the booths' telephone number and ring this on the spot to make sure you have the right number, tell them you have also the number of the police also. Ask them for festival, roadblocks or any other stond stort and that you will call them and the police in case there is. Let them escort you to an official taxi waiting outside and make sure that no one accompanies you! This could work!
