I need some opinions about...?

Okay my native language is Spanish. I speak English fluently, and i�ve been learning french for a while. I just entered Portuguese classes and it is pretty easy. Although the pronunciation is a little bit hard, i like it. I want to learn Mandarin so bad, but it is way to hard. I�m on vacations right now, i can learn two languages. I have nothing to do :( but when i enter school, it will be a little tough. Should a leave Portuguese? or should a have both languages?
