Срећно! - literally: "happily/with luck" (as these are synonymous in serbian), basically "[we wish you] good luck".

Све најбоље! - "[we wish you] all the best".

Лепо се проведи и пиши кад стигнеш! - "have a good time and write [us a postcard] when you get there".

The bracketed parts are implied.
