can't comment on rcsi (obviously) but i can comment on living in dublin. it is probably the most fun city i've ever been to and has the best nightlife vibe out of anywhere i've been (blows toronto out of the water, and every other european city i've been to with the exception of a few places in the UK). you'll have a great time here, but it's expensive and not always the easiet place to get things done. certain things like the peculiarities of the banking system take time to get used (or you just don't get used to them) but you learn to live with it all. take advantage of ryanair and TRAVEL. best thing i ever did.
