I always found it a north south thing when I have been to wales. Further north you are, the more likely you are to hear welsh spoken.

There is a pub/hotel I stay in up in Dolgellau and the barman there happily slips from welsh to english, depending on whether he is talking to the locals or not. Very happy to help out the the pronunciation of welsh beers too, if its not too busy.
