Trip To Ireland

I leave today for a week long trip to Ireland. I am going for work, but will make sure to have enough time for some personal fun. I will be traveling across the entire island from Shannon to Cork to Dublin to Galway and back to Dublin. I will also be making a weekend trip to England to see a Manchester United game.

That part of the trip could get a little pricey, but I have to go for my own sanity. If anyone has ever been to Ireland please let me know if there is something specific I should check out in Dublin.
