Advice for gap year between HS and college?

<p>My daughter’s school has agreed to let her take a gap year before she enters as a freshman. Her only obligations are to confirm enrollment next spring and to not enroll into any other college in the meantime.
She has some ideas about spending some time in Europe (studying 2 languages and working), and/or doing some of the volunteering/community programs in the US.</p>

<p>What I would like is advice from people who took a gap year between HS and college. What are you happy to have done? Do you wish you had done anything differently?
Thank you for any help:-)</p>
