Looking for a vacation spot near Curitiba 

Hello,

We will be attending a wedding in Curitiba in early April and would like to tack on a four day trip to another area not too far away. We are hoping for a "beachy" location that is off the beaten path, with more boutique type places to stay as opposed to large resorts. We're not big fans of large hotel chains or really crowded locales. We're hoping to find that "hidden gem".

We fly into Sao Paulo then plan to connect to a flight to Curitiba. It would be ideal if the vacation locale is fairly easy to get to from the Curitiba airport.

Thank you for your help!
