Tiền nào để sử dụng cho một tour du lịch ở Bắc Triều Tiên?

A friend in Australia is on a trip to North Korea soon, and has the problem that she can't get local currency in advance. Is there any way to do this before hitting the country, or is it perfectly acceptable to take Euros and USD? This is implied on at least one tour site however there's no indication that you can withdraw more while in the country.

Euro là đặt cược tốt nhất của bạn. Đồng won của Bắc Triều Tiên không chuyển đổi được, và tất cả các cơ sở cho khách du lịch giá và chấp nhận euro. Koryo Tours, nhà điều hành lớn nhất của các tour DPRK, nói :

Currency The official exchange currency in DPRK is now Euros (USD were taken out of circulation in 2003 but can still be used though we advise you bring Euros). It is possible to exchange other currencies (such as Pounds, Yen, Renminbi, HK Dollars) in the hotel but be aware that the rate will not be in your favour, better to change the money before entering the DPRK. We do not recommend taking in travellers cheques as they are difficult to cash. Economic reforms at the end of 2002 mean that the DPRK Won is now valued at roughly 165 won to 1 Euro. It may be possible to get hold of real DPRK money in the hotel but the best currency to use when buying goods remains the Euro.
