Once at St Mary's House you don't need your car unless you want to do some local sight-seeing in the surrounding countryside. Otherwise everything you need is within easy walking distance, the local supermarkets, the town square, the pubs, restaurants and bars and most importantly the beaches! You can get a train to Tenby from Swansea or Cardiff. From London's Paddington Station the rail journey takes around 5 hours with one change at Swansea.
