Favorite thing: Go to Muff and there you have cheap internet and cheap beers. He can also fix some food for you. Just drink here and you will save money. Maybe it is very small, but I just met one tourist here. It is a place for local people. perfect place to interact with the local people.
If you are with company then it appears ok to walk around the town you don't need a taxi unless you are off the beaten track. I walked around with my wife at night you get the odd boy begging and the usual shop vendors approaching, just keep your bag close.
Fondest memory: The Carnival Day was super all the drums and colourful costumes and dancing
