First time visiting for over a decade so there were a lot of improvements. If you are a vampire (like my girlfriend) then I don't recommend going in the morning or afternoon, try and get the evening session (if you are paying extra for the access to the higher areas of the temple). As you are leaving, they will try to tell you that you can't exit the way you came in, this is a SCAM! Just go back in the way you came otherwise they make you have to choose between an extremely long walk (over a kilometre) or pay for the electric shuttle bus. Also, when you've gotten back to the modernised area, there will be 2 guy sitting down telling you you have to turn left and exit through the markets, also a SCAM! Just push right through them otherwise again, you'll have to walk more and see more shops.
