The taxicab drivers are very united lately, and the price posted on the board when you exit the airport is the price that everyone charges...whether you live here or not...so I found out

I think it is $200RD or so. If you pay in USD you will likely pay more than the 16.8 exchange, hehe.
Once there, check out the Britannia pub on Pedro Clisante, where a lot of expats hang out. They will be able to provide a lot of good advice that will make your trip even better.
