Definitely a place worth visiting. The travel agency I found on Khao San Road with my husband is quite reliable (just across the road from the king burger, where the pedestrian street starts), the two young men are very good at English and the price is fair (in fact, the travel agency prices on Khao San Road are similar). A day trip, about 12 people's van, the big city and the summer palace include tickets and lunch 550b, all foreigners are with the group. The attractions in the big city are a bit similar. It was quite shocking when I first saw it, but I saw it too much and I didn't know that the history was still a bit boring. The summer palace in the afternoon is very good, very beautiful place. Unfortunately, the visit was not enough. There were about four vans that day, but in the end, there was only one to go to the summer palace. The local tour guide also said that there were not many tourists in the summer palace, so everyone would go to the big city, and the time to leave the summer palace was limited... If you want to go to the big city and the summer palace by yourself, it is not recommended. First, the attractions are scattered. Google map will make mistakes, the second is that the time control is not good, and the cost of the tutu car is also high. Compared with the group, it is easier and easier.
