we have done second seating twice- first time they were 6 and 9 and second time 8 and 11. we did it for the dine and play (or whatever it is called) where the counselors come and pick up the kids. we did not do it the very first cruise cause we were fearful they would not "last" until that time of day- but of course- there is food many places as well as the energy level is so high.
