Grand Hotel Parco dei Principi
This stylish 1960s hotel, designed by Gio Ponti, is all white walls and blue glass accents and funky geometric shapes; outside blooms the fabled Parco dei Principi, a lush 19th-century giardino, and paths lead to a romantic, bayside, Rococo villa—a splendiferous setting for the pool area. A shuttle bus connects with downtown Sorrento.
