The Children's Pass (ages 6-17) does not include the Roma Pass or Travel Card in Omnia, but still allows children access to all Omnia Card attractions. The Children's Pass does not include the Roma Pass or Travel Card for the following reasons: Anyone under the age of 18 has free admission to most museums, monuments, galleries, and archaeological areas. Children under 10 travel free of charge on public transport in the Rome capital region when accompanied by a paying adult.
