Sorry I can't be with you (sighs of relief all round) but having stayed in the area last year I can say to those who don't know it that it's great for walking* (if you don't mind a bit of mud), birdwatching, and you might be lucky(as we were) and see an otter on the canal or river. There's an interesting canal museum for those interested in narrowboats.
As I spent four years in various parts of Wales I can attest to the natives' tolerance of saesnegg! Seriously, you should get a great welcome.
