There are a lot of tuk tuk nearby the city.

I stay in Siem Reap for another week or so - to help with B4B project and assist at the Fair Trade Village to support their food hamper program

Yes, there is one area with steep steps at the back of the compound in which you can see the view from the top, but it is in no way mandatory to do. The steps up to the first floor if I remember correctly are a little high but are in no way near as challenging as the ones I mentioned previously. Also, you don't have to necessarily go inside the compound as the walk around it is plenty beautiful as well. There are quite a few gorgeous temples in the immediate area that don't have many steps either like Angkor Thom, Bayon Temple and Ta Prohm.

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!
