Translation of "sensational" into Portuguese

I never travel without my diary. One should always have something sensational to read in the train.

Jamais viajo sem meu diário. A gente deve sempre ter algo sensacional para ler no trem.

But for the most sensational spectacle, you have to turn the lights of the submarine off.

Mas, para apreciar um espetáculo mais impressionante, devemos desligar as luzes.

And you'll be as sensational as you were last year.

E estará estupenda, como o ano passado.
