So worth it! Arrive early before opening, because of the growing queue of waiting people. Also once inside try to head left first and up the stairs to the famous Forest of Resonating Lamps, because only 20 people are allowed inside at a time and the waiting queue gets longer through the day. If the line is short, just queue again, it's worth it! After that take your time, there is so much to see and even coming back to the same spot may be totally different the second or third time.
