I have never been over to ireland before, need some local advice 
I have 7 days from the 17th -23rd June I would like to do titanic museum in belfast, devils causeway, then southwest ring of kerry etc, in the car wife wont go on bike anymore long story
due to time its sort of a day drive to either ferry in wales as i live near London so that would only leave us with 5 days on the ireland would this be enough time to do the north and the south ????
My other option was to fly to belfast hire a car then fly home from cork or dublin, Ive read a couple of things about rentals not being allowed across borderers.
Really want to come over, any advice on travel times and literary appreciated.
