Can I visit Cambodia while traveling to Thailand for 16 days, and what visa do I need?

My experience is from 2015. If you're going to Cambodia by air, you'll get a visa on arrival for Cambodia, no need to get a visa prior to arrival. Cambodia uses US Dollar. If you land at Phnom Penh or Siem Reap, there are no scams at the airport. But if you enter by land, I've been scammed at the crossing south of Trat.

If you return to Thailand by air, you get a new stamp for 30 days. If you're only going to be SEA for 16 days, I recommend you fly and not waste a day or two in a crowded van on Thai/Cambodia's roads.

The Thai's limit entry by land to 2 times a year. By air entry's are not limited.

. You avoid the scams flying into Cambodia.

Mostly visit by road. Some transport companies handle your issue of both side n drop you sieam rip Cambodia. No need to worry.

Little wait you will get many options here from friends.

The limit of 2 entries per calendar year is only for entries by land border crossing.

There are no official entry limits if you arrive to Thailand by air.

Also, went there two weeks ago...so should be current information.

Well, scam might be harsh...plenty of sites trying to skim by charging more and just getting it for you...I think anyways. I went here and had no problem...official website. Went straight to immigration while everyone else was filling out forms.
