Did you solve it? Carry on camping

The solutions to today's hard ones

Earlier today I set you the following puzzle:

Six friends - Babs, Charles, Hattie, Joan, Kenneth and Sid - are going camping in France. They are travelling across the Channel on a magic carpet that can take only two people at a time. So, in order for everyone to get across there will need to be 9 trips in total from their starting point in England: 5 across carrying two people, and 4 returning carrying one person. (Magic carpets cannot fly empty, which is why one person needs to travel back. All the friends are able to fly alone on the carpet if need be.)
