I don't think Cambodia is open to foreigners yet.

Hello, we’re just there yesterday. Empty sites everywhere. You will still encounter small handful westerners tourists and asians. We took lots of good pictures with blank (no tourists) passing behind you. Still take precautions, wash your hands often, sanitized your hands/ lunch table/ utensils.

I did not see any.

We did 3 temples in one day and that was a good taste of that experience for us. $100US for a driver and guide, air conditioned car and water. The admission fee is $37US per person.

We went Monday for 1 night...of course the outbreak is still apparently fast moving but we saw few signs. We're back in Thailand now and face masks are much more in evidence here. Angkor Wat was packed with visitors from all parts of the globe with no suggestion of a slow down. We were fastidious with hand wipes etc as per normal when handling cash etc We passed thru temp scanners at both airport and train stations but that's all...enjoy!

Добрый день! К сожалению, не смогу Вам помочь, т.к. мы пользовались услугами англоговорящего гида. Очень хотелось бы сделать Ваше путешествие лучше, но, пока не знаю как.

You're not guaranteed the iconic photograph as even a light breeze disturbs the pond enough to destroy any reflection.

I would suggest sneakers. There is a lot of walking including stairs and slippery stone. Have a great time!

Ask your driver to stop off at ticket office on the way to temples.

In my opinion arranging a tuk tuk at the hotel would be the best option. In addition, if you fancy it, you can get a tour guide at the sites. Just ask for one at the ticket check point.
