Well about places to visit Alberobello (near Bari) or Castellana Caves (near Bari).
Going in Sicily by car you have to go in Calabria region, so why don't go to see Riace's bronzes in Regio Calabria?
For the hotels you can try to contact them: http://www.italyguide.com/index2.php?m=m…
send your schedule and I think they'll can help you.
