I am looking at the Buquebus website now... they ask you to click the country you are from. If I click Argentina, the price for Business is $933. If I click UK it shows as over $2,355 Pesos. And weirdly it shows different boat departure times (choose Argentinian resident and a 16:00 fast boat appears). Choose UK and it doesn't and instead a 13:00 fast boat appears. Are there different rates for nationalities? Or should I just buy the Argentinian one online? Or perhaps go to the terminal to buy my ticket to be sure I get what I want?
