You can spend the whole day here.

- Note when renting a vehicle to get around the ancient city: depending on the weather, if it's not too sunny or rainy, you should rent an electric bike. Golf carts seem to be suitable only when you go in a group (saving costs - 350b/h) or when the weather is unfavorable. The ancient city is very large, so don't walk if you don't want to get tired. - There are many places in the ancient city that can surprise you: such as the temple area or sculptures representing other Asian countries, not just Thailand. There is a rather scary place called the Ghost house, built as a way to share Buddhist teachings in Thailand. It's a bit haunting. - The architecture in the ancient city is really beautiful. On the map they give you when you buy a ticket, you will be explained which architecture is recreated from the original, and which is an artist's creation. Each area has an explanation board, but in some areas, the explanation is only in Thai. They suggest beautiful photo spots, but I find every place beautiful. They have an elephant riding service to cross the floating market for 1000b/20 minutes, but the floating market has no activities or people, so the most interesting thing is riding the elephant through the water. - If you want to take pictures in traditional Thai costumes, I advise you not to do any makeup beforehand but to rent clothes, makeup, and hair services there. They have a very professional area right at the entrance, and the price is not too expensive. Don't worry about getting hungry or thirsty as there are enough shops scattered throughout the areas. The staff at the ticket counter and inside are very friendly, and they even feed a stray cat. It seems to be well-treated because it is not afraid of strangers. - Getting around is quite convenient, you can easily get there by train. As soon as you get off at the last station, there will be a bus or taxi to take you in, and when you return, there is a vehicle from the ancient city operator to take you to the train station for 20-25b/person, but it will follow their fixed schedule.
