Oh sorry, where I used to work half the staff used to call the deaf workers "the deafies" and I assumed it was derogatory.
Anyway, you could do Snowdonia, Caernarfon Castle + Anglesey and there are boat trips on the coast there for afters.
Apart from that there is nothing in North Wales lol.
South Wales there is botanical gardens but is that worth driving a very long way ? not really although you can stay there most of a day.
Then there are beaches and coastline but again not a big attraction but the elderly love the peace and quiet
