Here is one solution that I would consider. When you receive your colored luggage tags, you usually get at least 4 sometimes 5 tags, see if you have enough to place on your daughters bags. If not, go to Guest Services and ask for extra tags, enough to place on your daughters bags. Place all of your luggage out with the same colored tags attached.
Then when they call you color tag to disembark in the morning, you can all walk off together.
