What is the protocol or ettiquet for invitations for a Disney Cruise Island Wedding? - disney cruise wedding

Our son married next year and has a Disney Wonder Cruise / Iceland Wedding Ceremony.We planned no further reception when they return home and the family and friends live far away. This does not even live in the same state as our son and future daughter right. We are aware that most of the friends and relatives unable to attend. But how can we manage the guest list, without violating anyone's feelings? I gave him a list of about 20 people. He said he called only a handful. Should we have messages to others? Our friends and family are scattered across the continent. Over the years we have seen and / or send gifts to hundreds of relatives and friends. We are a family united and close.
