This was my first solo trip to Poland. I was debating whether to go until the day before, thinking I might not get another chance, so I looked for a tour. Of course, there were no openings anywhere the day before, and I had given up when I found this tour on Klook! What's more, there were tours departing every hour from 7 AM to 2 PM, which was incredibly lucky. I received the voucher immediately after booking, and it specified the meetup location: across the road from the Mercure Hotel. I was picked up at 9 AM. On the day, I was the only person. I got into the car and was driven to Auschwitz, which took 1.5 hours. The driver's driving was very careful. Upon arrival, the driver handed me a paper ticket, and I went to the counter. Here, I received a sticker. The sticker indicated the guide's language and time. Mine was for the 10:45 AM English session. I said goodbye to the driver before the security check. We could communicate via WhatsApp. When I informed him that the tour had ended, he came to pick me up right away. The tour was a group of about 20 people, walking through Auschwitz and Birkenau. We traveled between Auschwitz and Birkenau by free shuttle bus. After visiting Auschwitz, there was a 15-minute break, where I used the restroom. It was quite crowded for women, so it was a close call. I was the only solo participant on the tour. Coincidentally, I was also the only Asian person. The guide explained everything in a consistently calm manner. There were no flashy presentations or videos. However, what happened there could be understood from the pictures, photographs, personal belongings, and remaining buildings. Photos and videos were allowed. There were some restricted areas, so I recommend listening carefully to the guide's explanations and visiting with respect. Since there's a lot of walking, comfortable shoes, rain gear, and water are essential. It was early July, but it was cold, so I also recommend bringing a jacket. On the way back, the driver asked where I wanted to be dropped off (perhaps because I was alone?). I was dropped off at the same kiss & ride as the pick-up, and then I explored the Old Town before heading back. If you're coming to Poland, I highly recommend visiting. You can participate alone; in fact, I think going alone is better as you can engage with the experience more earnestly without idle chatter.
