if you do not see the exit to the taxi when you pick up your luggage.say "TAXI" i think it is a french word. once outside, you should see a taxi que. pick out a taxi that is big enough for your load. make certain it has a meter. say"park hyatt, paris" this is another french word. make certain they will take 4, one in the front seat.

although this is very similar to what one would do from a washington airport, there may not have meter, and the driver probably will not understand french or english. he probably speaks Amharic. he should recognize the park hyatt dc.
