If you run out of FECs, you can change more US cash in any bank, though most places will accept US dollars as well. Quite often they'll be willing to change FECs back to dollars if you have too many of them at the end of your trip, and sometimes even buy your kyats back. In some tourist attractions there are special prices for tourists. As a part of the government's policy to prevent the locals as much a possible from being exposed to the bad influence of western tourists, only few, approved hotels in each city are allowed to accommodate foreigners. The latest pop music, for example, that many locals heard is Elvis.
Communication is a problem, because the government also stopped the teaching of English in schools.
Therefore, the ones who speak the best English are the elderlies, and it is not uncommon for young people to call their parents or grandparents to help them understand the tourists. DO NOT bring to Burma whiskey or cigarettes - so many people brought them in that they are no longer worth their price. Following is my itinerary - as long as only 4 areas are open to tourists, most visitors will follow about the same route, with minor changes. Just like we heard, the taxi driver was very friendly, and at the end of the ride, he offered us to change dollars to kyats. The rates in Yangon are higher than anywhere else in the country, so it's a good idea to change most of the money there.
