A lot depends on if you find Irish music/dancing a plus or minus. Your kids would probably enjoy the entertainment art RR, at the very least. Homecomin' may have less appeal to the children.
I don't think there's a wrong choice here, unless you don't like Southern cooking. Personally, I would choose Raglan Road, because there are more healthy choices. Homecomin' is not the best choice for someone who had four coronary artery bypass grafts!
Flip a coin.
