Turkey Visas were always easy. Just a quick stop at the booth, slide your credit card & passport to the clerk. He charged your card, stamped your Passport & off you went.
This seems much easier. And the same price, as I recall.

Cambodia has eVisa, too. But not for all ports. Since all Cambodian visas are single entry, we found that the eVisas were not good for all ports of entry. Ergo, while our eVisa for the Siem Reap airport cost about $56 for the 2 of us. Our visas provided by Regent for the cruise port of call (where the eVisa did not work) cost about $180 for the 2 of us. Kinda over-priced on Regent's side, I think.
