One year when my 3 boys were in the 9 - 11 ish range and didn't have smartphones yet, we went during Spring Break. Life had been hectic before our trip and while we were standing in lines I found out all sorts of things that had been going on at school and their other activities. Funny stories about teachers and classmates, what they were learning, they talked to each other about mutual friends, etc. etc. It was such a nice added bonus to spend that time together that I still remember it most about the trip.
