Campsite recommendation pls, where you can prebook 3 pitches together, South East England

[treadonthecracks]

We are 3 families, going on holiday together, a tent each. We really want to all pitch together, so the kids can play etc.

I know half term will be very busy.

We need shower block and reasonable loos. Laundrette/club house/pool/hook up would be nice but can survive without.

Can anyone think of a good site, where you can prebook your pitch number?

Any suggestions much appreciated.

We went with 2 other families to Hurley riverside and Wellington country park last year. Both allowed prebooking with pitch number. Reasonable showers and loos.
