The two round prongs are what they use in Europe.
As you can see, this is a quote from Explorer Ventures, not my own. Doesn't say "european" but does say two round prongs... i have adapters for both types that say Australia.
Adapters
Once again I quoted what was sent to me by Randy:
You will need an adapter & transformer from 220 to 110 to use US chargers and hair dryers. The plugs in the rooms have the two round small prongs, side by side
There are no dryers in the rooms

If this is an error it was not mine.
Ah! here is a new response from Randy...
I will check on the outlets? Now that you have me thinking about it they could be the slanted two prong or even the three. I was sure when I told you but to be honest I did so much international travel in the last two years I could very easily be mixing them up.
I have a small plastic case of all of the different prongs that I carry so I never check for my own personal purposes. It is the RCA foreign voltage adapter and it is great. I will check with Laurene in Oz to verify the plug.
