There are lots of taxis infront of the airport. the first line of silver car infront of the doors were quick to get our attention,and business.We paid 990uR for the trip to town...the black and yellow cabs on the return triponly charged us 550UR...a $25.00 lesson.
There's a bus line that goes to Punta Carretas Shopping.
The bus is DM1 and takes about 40 minutes to get there and runs every 15 mins aprox during daytime.
There are another bus lines that take you to Tres Cruces Bus Terminal or Downtown and then you can take a city cab.
An airport cab may cost you usd 30-40. The bus ticket is USD 1...
The taxis in Montevideo are not expensive, you can have a good road around for less than $100 pesos (U$4,30).
Just watch out if they are being honest with you, once my running was supposed to cost me $39 pesos, I gave $50 and got the coin back, but I didn't check if it was correct and when I realized he gave me back only $1 peso.
Taxi is a good and not very expensive way to go around Montevideo; the cars are easily recognizable (painted in black and yellow, with a light sign with the word "TAXI" on the top!!!) and you can get them at the street, at the "taxi stops" or call them by phone. The cars have taximeter, so you will pay what the machine registers. The costs are higher during the night and on weekends. As usual, the Montevidean taxi drivers are also psychologists, politicians, soccer coachs, meteorologists, so you can talk with them about a lot of points.
El taxi es una manera buena y no demasiado cara de recorrer Montevideo; los coches son fácilmente reconocibles (pintados de amarillo y negro, con un letrero luminoso con la palabra "TAXI" encima!!!) y los pueden abordar, en la calle, en las paradas de taxi, o llamarlos por teléfono. Los coches tienen taxímetro, por lo que pagarán lo que indica el aparato. Las tarifas son más altas por la noche y durante los fines de semana. Como suele ocurrir, los taxistas montevideanos son también sicólogos, políticos, entrenadores de fútbol, meteorólogos, por lo que pueden hablar con ellos de cualquier tema.
Taxis are available throughout Montevideo. They are cheap and safe. If you want to take a cab just extend your hand and it will stop right besides you.
There are also some taxi checkpoints in the city, you may want to know where these are near your hotel. Don't arrange a fee before taking the cab, just wait for the meter to tell you the price. Tipping is not expected but if you want to do it it's ok.
