If you plan to visit the city centre you'll find it a 10-15 minute walk away.  Alternatively you could catch one of the regular buses that run from just outside the hotel.  But whatever you do, don't waste your time driving as you will never be able to park.

Once you're in the centre you have lots of shops and of course the cathedral and its grounds.  When we last visited there was an entrance fee, though I don't know whether it's mandatory: £9.50 (concessions £8.50).
