Do you like shopping?
Lucca has many beautiful shopping streets you can stroll along.
If you want to visit more upmarket boutiques, a day trip to Forte Dei Marmi is highly recommended, especially combined with the beautiful Versilian sandy beaches and nice restaurants that Forte Dei Marmi boasts.
How about a day trip to Florence? Both by train from Lucca and by car, Florence's shopping streets are perfectly accessible.
