Budget does not have an office at the terminal D of the Tallinn port! There is HUGE mistake on the websides of Kayak... Pick up was very stressfull and unpossible to make. Nobody pick the phone number mentioned in our reservation. We had to take a shuttle to go to the airport, then it was easy, but in case that we order a car with pick up at the ferry terminal and receive confirmation with these informations, we should get a car there, not at the airport.
