Accompong: your link didn't work, so I will ad my 2 cents...(pun).. I find it much better to exchange because not all establishments take U.S currency and most times if they do you will get JA in change. U.S five's and and ones are good for taxis and beers but ones can be bulky to carry. Having JA currency just makes less hassle. Case in point: I was trying to purchase tickets to a show once and all I had on me was U.S. The vendor began to haggle with me about "his exchange rate" LOL. I ended up paying about five U.S per ticket more than I needed. If I had JA on me that day I would have saved ten bucks.. Don't exchange at the Airport the rates are normally too high. There is a cambio in the circle that normally has good exchange rates. Some of the hotels will exchange as well but check the rates. Never take an exchange from the guys offering outside the cambio.
