Ireland is a wonderful location to visit - I highly recommend it as a holiday destination.
There is so much to see and do in Ireland - that you will never have a dull moment while on holiday.
I visited Dublin there a while back - and I have to say I had one of the best break ever. I spent two days taking a quick look at all the main tourist locations such as Dublin castle, Trinity College, The house of Lords etc - although I only took two days I really should have spent a week doing so - and I will return to see what I missed out.
I then spent two days just wandering around the city its self - doing some shopping and enjoying the culture. The people are really friendly and very helpful. You really must sample the night life it is just out of this world - the ’crac’ as they call it is super.
