Kevin, I want to take the opportunity to thank you for all the information you have posted, here and on the Scandinavian Message Boards. I really enjoy reading the results of your researches into the Danish Newspapers.
The wedding of Louise is described in James Pope-Hennessy's biography of Queen Mary. It was overshadowed by the illness (typhoid?) of Prince George William of Cumberland. The state ball and other festivities were cancelled, but fortunately Prince George recovered. Poor Louise did not have a good start to her married life.
Sadly, none of the beauty and charisma of Queen Luise of Prussia seems to have been inherited by either Princess Louise or her mother, Queen Louise of Denmark.
