A trip to Buzios, Arraial do Cabo and Cabo Frio - Brazil

What a wonderful trip it was I must say. Of course, there were some downs as well, as expected. We started off with Buzios. 

If you ever plan to travel by bus in Brazil, opt for Buser, kind of uber for buses. By the time you are reading this post, there might be some more apps available of this kind so keep looking. Service is excellent for very cheap price, as you might be looking. Here is the code which might get you even more discount,

So now let me say some more. SO we took a buser from RIO - Cabo Frio. Then either take an Uber to buzios, costs like 35 to 40 reais. Or go with Salineira bus, costs about 6. Both are fine.
