First, if your ticket was bought when your daughter was a child, and a couple of days remain after she turns 10, I don't think anyone would think ill of you for allowing her to finish off the ticket before purchasing her first adult ticket.
If you would be uncomfortable with this scenario, a younger child should be able to use the ticket. When I buy a ticket for one of my grandchildren, I ask for the ticket to be issued as a "child's" ticket, rather than including the name. I didn't have any problem with this, even when we were staying in a value resort. I just did not have the ticket added to the resort key.
