They are pretty cool , We went for the 3 day pass at Angkor and only seen a fraction of what is actually there, some people spend weeks. Way to long for me, they were all starting to look the same after a while. plus its fookin hot so the best time to go is at sparrow fart but the negative of that is the place is literally swarming with punters, Anyway i saw them 30 years ago and seem to recall there was always a vendor hovering nearby to sell me a beer, even inside the temple complex, Looks like they have cleared the vendors out. Damn shame Really. Spoilt my cultural experience.
