Is there a good way to say (write) to a co-worker "Have a nice winter break!"? It would be referring to the break between semesters at a university. I could say "Buone vacanze", but I've heard that usually refers to summer, or when someone is actually going somewhere. I could say "Buon Natale", but the break also includes most of January, and "Buone vacanze invernali" sounds awkward to me. I would appreciate some help with this. Thank you!
