Loads! Greenacres is a very large caravan park run by (I think) British Holidays. Clientele is a mix of owners & visitors. Facilities are excellent. There is a large completely refurbished clubhouse with an adult lounge, cafe a new big showbar. Also indoor pool, kids climbing area plus (inevitably) slot machines. Also a Burger King but the chippie up th eroad is better. Watch out for pass prices though - quite high from what I remember.

Greenacres is only separated from the huge beach by sand dunes - easily walkable but you can drive onto the beach if preferred.

Can't comment on accommodation as I usually stay at friends - check th eweb for owners offers. I've never stayed at the Haven (I know it as Butlins Pwllheli) but reports I have read here sound like it's only improved marginally since the Butlins days. Go to Greenacres!
