Cheers for all the advice peeps. We eventually managed to get into a place in Porthcawl. It is £34 a night each for B&B, which in a 3 star hotel is practically free.
Thanks again for taking the time to share tips. One final question...is it worth a taxi ride into Cardiff to have a night out on the Friday or is Bridgend/Porthcawl good for a night on the beers?
Cheers
