We are traveling in early September. We have an "extra" day and are trying to decide where to spend it! Right now we are in Rio for 3 nights, Paraty for 2 night, Curitiba for 1 night, Morretes for 2 nights, and then on to to Ilha do Mel for 3 nights. Is 3 nights (2.5 days) too long on Ilha do Mel? Should we spend it in Paraty or Morretes instead? Any suggestions would be greatly appreciated!
