What should my husband pack for 5 days in Ireland in April?

We’re going to Bunratty Folk Park, Kilkee, and the Killarney National Park for the Gap of Dunloe and Kate Kearney’s Cottage. We’re staying at town & country B&B’s.

Warm clothes, a raincoat and hat, and maybe an umbrella (called a brolley in Ireland). It’s pretty wet and chilly in April. Layer your clothes in case you get an unexpected warm spell.
