I also self-booked and made the trip for the 2015 event and it turned out to be one of the best times I ever had in many years of hockey related travel. The arena itself is clean and modern with excellent sight lines and surprisingly knowledgeable fans. Then there's "Mother of All Hockey Bars" (no exaggeration) on the ground floor of the arena building. If you do the right thing and make the trip, be sure to take an extra day or two to take a tour of Belfast and/or the Antrim coast. Another must is the Titanic Museum, located right on the slipway where the Titanic was built (and steps from the arena). And If you have time, take a bus or train down to Dublin and beyond. Really people, it's a great trip.
