I believe that the Danish and British RFs are actually in quite close contact. Just because there aren't many 'official' meetings doesn't mean that they are not in contact. I remember seeing Queen Margarethe on the BP balcony at a Remembrance Day ceremony a few years ago. I also know that she was over at Balmoral Castle for a private visit some years ago. They are fairly closely related (? 3rd cousins), so I think they probably communicate quite amicably about such family matters.
It is true that following the First World War the 'Windsors' withdrew from contact with most Continental Royals - there was even a big problem with Prince Philip's 4 sisters all being married to German princes, and none were invited to his wedding in 1947. The Queen herself is never seen holidaying abroad, although she has attended many important birthday and other celebrations of fellow senior European RFs. She is also particularly close with the former Greek monarchs (and Queen Anne is a sister of Queen Margarethe), who have largely lived in London since they were deposed.
As to the protocol of bowing/curtseying to those higher up the social scale - this is so much inbred in all RF members that I don't for a moment think it causes them any problem. Only if you are the Monarch do you not have to stop and think, because you know that every one is either your equal or your inferior!!
