Recommended Sites in East Anglia

Old Van New Trips

So I have finally talked my husband into buying a caravan after reliving my caravanning experiences with him when I was a child.  We now want to take the caravan away for a weekend to get used to it and also book some holidays up for next year.  Can anyone recommend a great family friendly site in East Anglia preferably with a swimming pool.  I have searched the internet but not sure which park to go with.
