Wow you live in Ireland? That's kind of cool. Well even though I live in Florida and really close to Orlando, I have only been to Disney World like 3 times I think. Also I'm still sticking to Kingda Ka as the best rollercoaster ever and if not, then definatly the most thrilling. Just check how it looks.
Wow look at that thing, it's as high as a 45 story building!
