Ther than the fact that the trip has been rescheduled, do we have any information that would suggest that she is determined to attend ?
I don't know if she is determined to attend, but i'm glad that William and Catherine have been stepping up contacts with other European royal houses. They have been in official visits to Denmark and Belgium (in the latter, more than once actually) and Catherine has been to Luxembourg. As the future king and queen consort, it is important that they develop a relationship with other young sovereigns or future sovereigns.
