Hi there! We will be on the Explorer 4-12 also! It will be our second time on the ship and we were also on the Voyager 3 years ago! We have 3 boys, ages 15,13 and 10. When we went 3 years ago, the boys ate with us on formal nights, but last year they did not. They made sooo many new friends and they had dinner with them and hung out playing sports and socializing! They all had a great time! On each cruise, we had late seating and they really just wanted to go hang out! It was never a problem and there were so many things for them to do! They wil have a blast!
