Creme If you do need to get to Ireland more cheaply there is also the option of the train to Holyhead and the boat. My DH really enjoys that journey. I've never tried it, but it's much much cheaper.
My ds dealt really well with all the anticipation of Christmas and I was pleasantly surprised. Christmas Eve was very quiet almost as if we were all bird-watching. Then we were up early on Christmas Day and earlier still on Boxing Day, but really, so far, so good.
They're watching Gilbert and Sullivan videos now while I potter about.
Thanks for the reminders not to get taken in by sales. I keep thinking I ought to be looking for bargains, but I'd rather just have a holiday. 
I was given four bird boxes for Christmas, which I'm quite excited about. A nest to watch would be lovely.
