When you come out of the station, walk all the way down the hill to the Seafront, you can't miss it, it's straight ahead. When you reach the pebbles, turn left and you'll see the pier, perfect on a summer evening as the lights and music will be playing, wander up it, have an ice-cream watch the rides, wander back down again. Turn back left again to come back to the road you walked down from the station, but this time go down the steps right on to the beach and wander past all the little shops, cafes and art galleries in the arches. Much better than sitting in an airport hotel for the evening
