Thank you! For some reason I could not find this

They don't make it easy!

Even with advance tickets, go earlier than your reserved time. There must have been 1,000 people in line when we got there. There were a few different lines that all seemed to merge into a mess. Being at the end, there was no way to tell where you should be and there were only a couple of helpers way at the front of the line. It was quite disorganized. The palace is well worth the visit though.
