I have and think I have the correct answer but have two letters left over at the end!

You mean you got the character as an anagram, and used that to get the order? Yes, of course that would work equally well! I admit that I solved two of-the sequences by getting the landmark answer first (from the remaining sequences) and working backwards.

Have you translated the Morse code yet?

Yes I solved that then realised the actual translation didn't help me so looked at how I could get the clusters of letters in the right order and used the initials. And yeah for number 7 I worked it out from the location on the map then had my dad explain to me how the puzzle worked.
Has anyone bothered to work out the binary code yet, I don't have the patience to translate that!

The binary code is an extra - it provides the equivalent of the message inside the Christmas card. It doesn't relate to the other puzzles so is not required to complete the quiz.

Later on, when everyone’s finished with it, can you let all of us lazy people who don’t want to translate know what it said? Or is that in the link from the QR code?
