It will take 2 or 3 days to visit all the temples.In ancient times, Angkor Watt was one big city with all these temples inside.It's amazing how they ould build this all without any power from machines or what so ever.U won't regret it if ur planning ur holiday over there.Have fun ,ladies and  gentlemen.Should u have more questions to ask, u know where 2 find me,lolz. Take care all, have fun and be safe !!!
