We will be going to Dominica as part of a cruise in March 2013. Has anyone hiring a taxi to tour around, if so what was your impression, what is an appropriate amount to pay (or do they charge) and where would you recommend we go? We are there from 9:00am - 5:00pm so not a long time. We will be travelling with our teenage daughters so there will be four of us. I am also assuming we would need to pay them cash and would American money be approrpiate?
