For most events at NRG Park, children two years of age and older require a ticket for entrance.  Children under two on the lap are free, but this is not a blanket policy for all events.  For example NCAA events require that everybody must have a ticket.  For many family shows the rule is children one year of age and older require a ticket.  RodeoHouston’s current policy is children three years of age and older require a ticket. Please double check the policy for each show.
