Worth considering.
I booked with thetraveldepartment.ie. This company advertises in the Irish Independent from time to time. I have travelled with them three times and so far so good.
Sometimes their website will not load so I have to go in to Yahoo and key in their name and then select, a pain in the a**e. If you register they will e mail you special offers. I flew in to Ljubljana, I think they have a weekly flight to Dublin on Saturdays. I also went to Pula which is a good distance from Portoroz time wise, mainly because the roads are small and winding. Unfortunately when I was there the shops were closed so not much of an atmosphere. Shops close at 1 p.m.on Saturdays until Monday. Dave, I will have a look at Trieste and Klagenfurt for next trip.
