We are now in Paaguay and it was the longest border exit from Brasil ever. 2 hours or more. The lady was busy. She did apologise in English so we will let them off. Paraguay was difficult. You need to go up the hill to the right of the border gates. Go immediatly through and hang a right up to the car park then into the office block. We were guided by a young lad tasked to get us to the correct office and they wanted to see the Brasil exit paperwork!
