It may always be a developing country, and the tour guides may not be able to tell you a lot of things in great detail. However, the point-to-point transportation basically takes you to all the places you want to go. The itinerary is tight but not rushed, making it worthwhile to spend a day on it. In the elevator waiting area of the building where the observation deck is located, there is a small shop. I sincerely recommend the chocolate in the photo, it's cheaper and more delicious than buying it at the airport! We ate before the last itinerary to the mosque, so we were quite hungry. I suggest you bring some snacks with you. You can wear short sleeves when entering the palace, but you must wear long pants. You really need to wear long sleeves and long pants when entering the mosque, but you can borrow a black robe, and the tour guide will help you borrow it. If you need to go to the restroom on site, ladies must line up a little earlier, I don't know why most of the women's restrooms have so few stalls. In addition, the line in front of the palace is basically in direct sunlight, so it's better to bring a scarf to wrap yourself up. People come out to distribute water at the palace from time to time, remember to take a bottle so you don't get heatstroke.
