Start saving, Eileen!
And before you decide on exact dates, check with Rita (or anybody else in Ireland), because now that Ireland is going to have it's own national quiltshow it would be a shame if you go just before or just after and miss it.
And if that doesn't work, there is always 'Festival of Quilts' (largest quilt show in Europe) every mid-August. The location is right next to Birmingham Airport and a railway station, with plenty of hotels, so it might be something to include in your itinerary.
