In advance, Ctrip booked a London Eye Expressway + 4D experience ticket. Once around the London Eye, hundreds of people lined up to collect tickets from the official ticket office in the rear building of the London Eye. (If you buy tickets on the spot, adults are 37 pounds and children are 26 pounds. If you add 10 pounds per person to the speedway, Ctrip's 187 yuan fare is much better.) After collecting tickets, I watched a 10-minute 4D movie in the building. It was about a pigeon flying over a classic building around the Thames River, with wind and water dripping on his face. Fortunately, I bought a fast-track ticket, which can be boarded directly from a queue under the eyes of London. There are about 20 people in each cabin. There is a bench in the middle. It takes half an hour to turn around in the air. The fully enclosed glass cabin can see Tower Bridge, Debris Tower, St. Paul's Cathedral, Big Ben Bell and so on. When you are about to return, the radio will inform you to stand in the footprint area on the ground. There is a big camera outside the cabin to take a picture of the people in the cabin. The London Eye was opened in 2000 with a total height of 135 meters. At night, the London Eye will become a huge red halo. It has become a landmark building in London. There are many tourists from all over the world. According to other strategies, there are many thieves. We must pay attention to our bags.
