It's a bit more complicated than that...
Does it have a mediaeval cathedral with a distinctive octagonal chapter house? If not (because that's where the wedding will be) I don't think I'll be entirely convincing....There's a river and a bit of Cardiff called Ely. We cross the river on the FNRttC. You could just say you got the wrong Ely...

Nothing wrong with Taffs Well. I used to get the train from there into the 'diff every day. Not that I actually lived there, you understand, but on the other side of the valley.
