We flew into REP from SIN on Jetstar, arrived at 7:00 AM, only our half full flight, and it took an hour to get out of the airport.

You need a photo for the visa, but for $5.00 they will make a digital copy of your passport photo. Then they take your photo when you use your visa at the final counter. Go figure.

There is an ATM machine right at the place where you line up first to submit your application and money. The ATMs all dispense US$ in Siem Reap as far as I know. The visa is paid for in cash, US$. Don't forget about the $25.00 fee you pay to exit Cambodia by air when you leave.

Phnom Kulen was the coolest place we went. Great swimming in the waterfall. Modern active temple interesting. Lingas very cool. Our guide's family all accompanied us and brought along a great picnic we all shared in one of the huts designed just for that. You can buy shorts and towels and shirts up there right next to the stairs to access the fall.

I'd go directly to Angkor Wat from the airport, enter through the back for a different perspective, and when you are through it all, turn around and marvel at what you just walked through. Angkor Wat faces west, so sunrise is not a great photo op imo, though it's a popular way to start the day. Then head out to the Silk Farm and have lunch there. Take a car, as it's quite far in a tuk tuk, not to mention hot and dusty.

There are so many other temples in the area that it would be a shame to travel to Siem Reap and only see Angkor Wat.

On Day 2, with Angkor Wat covered on Day 1, see the Angkor Thom compex in the morning, and definitely see Ta Prohm as well, probably in the afternoon.

On Day 3, on the way to Phnom Kulen, stop and see Banteay Srei...one of my favorite temples. There is plenty of time in the day to do that and it is very near to the turnoff to the access road to Phnom Kulen.

We used Ponheary Ly for 5 days, and her brother Dara for 1 day. Both were very, very good and I can recommend them without reservations ponheary at yahoo dot com. They were both informative, personable, and easily adapted to our every whim. Great driver, too. We had a very nice school visit as well...you might also be able to fit that in on the Phnom Kulen day if you like as there is a school that is supported by the PLF (www.theplf.org) very near to Banteay Srei.
