Depends on what part of La Romana you want to go to ..To Casa de Campo at day or night it is between $90 and $95 for one or two people . For the town it may be $5 more and they are a bit hesitant at night . They like to use the by pass to Casa de Campo . This is pretty well the set price and the taxi drivers normally have a discussion amongst themselves to see who wants to do the trip . It is only between one hour and one hour and fifteen minutes
