Pour yourself all the Guinness you can handle at this Dublin hotel

Every day is St. Paddy’s day in Dublin’s new DoubleTree, which -- following a recent $21.6 million renovation -- now rocks a pour-your-own Guinness tap in the Executive Lounge. Seriously; check in, pop by the lounge, help yourself to as much Guinness as you can drink. It's that simple.

Okay, almost that simple. You'll still have to be a Gold, Diamond or Executive guest -- otherwise, you're gonna need to sneak in.

But when you do, you'll at least find a video tutorial behind the tap that walks you through the six steps to pouring the perfect pint, ensuring that by the time you check out (and or are booted from the lounge), you'll be a "certified perfect pint pourer".
