Haggerston Castle caravan sleeps 6 11th - 15th September £130 including passes

Bronze, i assume that's not their top tier

If you are looking for a good deal, you could also try Parkdean holiday parks. We've booked a week in Trecco Bay in South Wales (biggest holiday park in UK) and the facilities and activities there look practically the same as what you find at Haven. The main reason we chose it was could get a nicer caravan for a lower price. We got one with an ensuite to the master bedroom for £819 and then I got £40 off that with a voucher on Coupert. Haven's Bronze and Silver caravans don't seem to have ensuites and after last year, I wouldn't stay in a Saver caravan again as have been spoilt by staying in wider caravans so didn't like it. Coupert is something which saves in your search bar and automatically searches the internet and tries all of the coupons till you get the most money off your basket at checkout. I have saved loads over the years with it. (edited)

No the wonder parents book holidays out of term!
