We recently got an RSVP back from someone that has a child (9-yrs old) but for the menu choice, they did not pick what was labeled as the kids' option but picked something from the adults' menu. There is a big difference in cost between adult and kids pricing per person (over $200) so I'd like to go back to them and let them know we changed it (saying "hey, saw you picked something from the adult menu for <child>, but we updated it to the kid's choice!"). However, my fiancé is concerned this might annoy the parents. Any advice on how others would handle this?
