Ah lad that sounds like me 5 years ago. I don't travel with work anymore but I used to be in hotels every week for at least 1 night. Some people used to get sick of them but there's nothing like a steak and red wine (on me own) in a hotel . And a couple of pints after it. Yep Guinness can be hit or miss but your one looks nice . Although I would rarely get a dodgy pint of the black stuff in Dublin. Its always top class up there
