We are travelling from Holyhead Port to Longleat Centre Parcs in the Summer. Hoping to stop off en route for a night or two. Is there anywhere that you would recommend? We are 2 adults and 3 children aged 8-12. Looking for something not hugely expensive. Usually our problem with hotels is that we have to book 2 rooms but we are open to a family room or self-catering. Bonus points for something quirky or unusual. Thank you.
