You definitely have great ideas. I have also heard that you can "buy" name a star after someone, maybe buy two for each of them. Another idea that I always love is to make a donation in their name to a charity or issue that is dear to their heart, ex: zoo/animal shelter by sponsoring an animal, a local food shelf, a children's organization (a great one is Greater Minneapolis Crisis Nursery), a health organization like Children's Cancer Research Fund, maybe buy a brick from some organization building, the list goes on...it sounds like they have everything, this could be a nice way to give back to others on their behalf...GOOD LUCK!
