Hi, I found that getting off at the right place is another challenge. There's no stop indicator in the bus.
I took Aeroporto Executivo, bought a round-trip ticket with a help of Google Translate. There's a manned stand in front of the bus stop. You can use credit card (contactless ok) to pay. Their round-trip ticket is valid until July 31. I used AndOsm on the bus to ensure I didn't miss the stop. Their first stop (train station) is actually walkable to the venue. The bus detoured to another hotel nearby. I got off at the last stop (Shopping Estaçáo before heading off to the airport) but I found the bus took too much time driving around the city center. I am at the hotel now! Yao Wei (This email is sent from a phone; sorry for HTML email if it happens.)
