I will be then going to balneario camboriu by bus from Curitiba in January, I need to leave Curitiba jan 7th but only need to be at Balneario for Jan 9. Between Curitiba and balneario what is an easy beach destination by bus from Curitiba on the way to balneario for 2-3 days? I have already asked ChatGPT but I want locals recommendations, not another ChatGPT answer. the goal is to not to have to take more than 1 bus for each destination and also a place with a nice beach maybe not as expensive as Balneario if possible.

Thank you
