I tried the smaller earth link and it gave the best price so far but it was in euros with no option to change. I also tried Andy’s site and that was the next best price. We are only going to have a car for 2 days, to get to KSC and a shopping mall day. Other than that if we need to get around it will be an Uber
It does quote in EUR and you get charged in USD. the conversion is shown if you choose to pay on arrival, which I think is a better idea as if you find cheaper you don't have to worry about
