Site suggestions for a first timer?

After about five years of persuasion my wife fnally agreed to us buying a motorhome which we pick up in about two weeks time. She is stil perhaps not entirely convinced and so I am doing all the research possible to find a site in Norfolk, Suffolk of Cambs - not too far from home -  for our first 2 or 3 day stay in mid May which will ensnare her into the hobby and not put her off. Does anyone have any suggestions. All advice greatfully received.
