GOOD TOURING/ HOLIDAY PARKS WITH ENTERTAINMENT ?

Hello everyone

I would like to ask if anyone knows a really good clean touring site/ holiday park  in NORFOLK ,ESSEX , KENT or DORSET with evening entertainment for the kiddies 

looked up quite a few on trip advisor and was dissapointed to find the ones i thought looked good with their glossy brochures are really bad dated and dirty 

We are new to carravaning and have booked our first weekend away to seacroft site in cromer in september am a little nervous as i really dont want to be dissapointed .as its a bit of a drive from essex 

Are looking for a few new sites for next year any ideas will be really welcome 

thanks claire x
