Tickets for the Alhambra Palace (including the Naples Palace) need to be bought 2 months in advance. I bought them as soon as I got my visa, but I didn't get them. I saw this 12:00 noon session, the Alhambra Palace (including the Naples Palace) + manual English explanation, and I got it, although it was a little expensive. The ticket has a QR code, and there is no need to exchange tickets. The meeting place is at the coffee shop, so you need to pay special attention to the meeting place and try to arrive in advance. The convener of the meeting did not hold a sign, nor would he actively call people. You need to find it in a large crowd by yourself. It was a headache, but fortunately I found it before the meeting time. I entered the Alhambra Palace on time at 12:00, including a total of 5 people in the group. The British tour guide was very friendly and took everyone slowly and entered the garden first. I entered the Naples Palace on time at 14:00, the explanation was detailed, and she also helped us take pictures. The whole process was very soothing and ended at 15:30. The experience is very good! (If you are traveling independently and your English listening is good, it is recommended to choose this project as the best)
