Contacting Astros Guest Relations for son’s first time at Daikin Park

With our pilgrimage to Houston fast approaching, I thought to contact the Astros Guest Relations or whoever to see what they could do for my son as this will be his first time at Daikin Park and first time seeing his beloved Astros playing in person. He's already planning a sign saying he flew from Germany to see the Astros play, but I would like to see if the team can do anything for him to make his first time there even more special. Does anyone know who I could contact before arriving at the ballpark?
