HELPFUL TIP FROM John Smyth: "If you're stuck for something to do ... that doesn't involve sitting in a beer garden guzzling pints [not that there is anything necessarily wrong with that - just try to have breakfast first], you might want to wander over to Emo Court near PortLaoise for the National Country Fair - plenty of photo opportunities and probably very few Dubs [they're all in Galway]." Or in Cashel, the spot that 100% of all tourists rate as "worth visiting" on 43 Places.
