Anyone who goes to Dublin with a little time to spare should take the Belfast day trip. It's a quick 2,5 hours bus travel, with stops at the museum of the conflicts between British and Irish, at the HMS Caroline (a war ship built in the same fabric as the Titanic), at Belfast dowtown and at the Titanic Museum. It was worth every penny! Extra kudos to our guides, Barry and Jerome, who knew everything about everything we wanted to know (and more!)!
