We returned from our
Croatia trip last July. Briefly, we flew to Dubrovnik, then took the ferry to Korcula, Hvar, and finally Split, before flying home.

The ferry from Italy carries cars, and also has sleeping accomodations.
If you have 5 days, limit your time to 2 places.
From Split to Hvar, it's about 60 minutes if I recall.
Since it's off season, look closely at the ferry schedule. Also, many restaurants will be closed.
