Hi
I just want to endorse what Lesley & Damian have said.
Chaple lane is a Caravan Club site, & Kingsbury water park is a Camping & Caravan club site, I believe that both sites accept non members.
Chaple lane is south of the city J3 M42.
Kingsbury Water Park is north east of the city J9 M42.
Both are very nice sites & about 10 miles from the city center.
