I spent a little over two weeks in Croatia (and Bosnia and elsewhere) in May. I spent nights in Rovinj, Lovran, Zadar, Trogir, Dubrovnik (then through Montegro and Bosnia) and finally in Plitvice Lakes and Samobor. This was my second trip to Croatia - in 2009, I also visited Zagreb, Baska Voda, Split, and Korcula so didn't feel the need to see them again. (But Dubrovnik and Plitvice were return visits this time.)
Here's a link to my trip report, including pictures and videos (starting with the Croatia portion):
