I'm just back from a stay in the Kenmare Bay Hotel...it's a nice hotel...about 3 star I would say. They are having a wedding fair either this weekend or next weekend so it might be worth your while having a look at that?
I know plenty of people who haven't got married in the bride's parish. I will be getting married in my own parish that I grew up in coz I love the little church there and I couldn't think of anywhere else to get married. But I know loads of people who don't do that. It's just personal preference really! Good luck with the venue hunting!
