Croatia from Shannon

Has anyone flown to Croatia from Shannon? The return flight is (as far as I can work out) via Belfast. I was wondering how much hassle it would be with children - whether it is a touchdown and fast turnaround or if it involves plane changes etc.

The flight lands in belfast for about 30 mins, there are a good few free seats free untill you arrive in shannon so you can spread out.......but it does make the flight extra long.
