Where should we travel in Croatia?!!!!!?

If you want to stay on the coast and enjoy sun and see, go to coast: Split, Dubrovnik, Zadar. There are lot of historic monuments in all three of them, enough to see for at least a day. Then those boat trips around islands. Brac and Hvar, they are just beautiful. Korcula is island of Marco Polo, also beautiful. On Pag there are wild summer DJ coast parties, something like on Ibiza (google for Zrce beach parties). Plitvice will also take one day to walk through. Now, on the north part of coast is Pula, ancient city, has Roman amphitheatre and several museums. Zagreb, the capital, also has several museums, art galleries, history from medieveal period. I think that 9 days will be too little to go around all that :) You have regular bus lines for all these cities, you have airports in Zagreb, Split, Dubrovnik, Pula, and train connects Zagreb and Split.
