Activity for Cassie

I do not need anything materialistic so I do not feel the need to have a registry. I do want to have a registry for my honeymoon does anyone have a specific place they registered to get just money for their honeymoon?

I have 5 nephews ranging from 10 to 2. The two youngest I will have as ting bearers. The oldest three I am not sure I thought about doing some sort of signs for them to carry. Any idea will be appreciated.
