my parents went overnight for a business meeting a few months ago. Were impressed with the facilities and food and are considering going back for a holiday. They didn't have children with them to consider though.
Yes I've been a couple of times. Check carefully whether they've got stuff on for children, its usually aimed at adults but they bring stuff in for children in school hols and for bank holiday weekends eg: May day weekend. Entertainment can be a bit adult after 9pm. Accommodation fab in the hotel but very dated in the bungalows (which they are doing up) but they haven't done many of them yet. Its got a small ish swimming pool and a beauty salon which provides treatments.
