SIGH
I wish I was going back to Ireland in November. I miss it.
Bring warm clothes, and a light raincoat.
If you like good food you should try to swing by Kinsale in County Cork; apparently the epicurean capital of Ireland. Donegal in the north west is really beautiful, as is Antrim (though this is in Ulster, so officially part of the UK).
Dublin has lost
some of its charm, and is now very expensive and mercenary with much greater levels of consumerism than in the past, but it's still a great town. Check out the Dublin Literary Pub Crawl (if you haven't already) -

Have a blast mate. You'll enjoy yourself.
