Hey Bobby- I so know what you mean,As a mom of 3 boys and a little girl.

kids get bored. Nothing wrong with bringing something to do.Either for early morning wakers- or late night fun.Or the waht if's- what if someone gets too much sun,and needs to stay in for a bit. or not feeling well.I say always better to come prepared.My boys are brining their game boys and stuff in their backpacks for the plane.I am buying a portable cheap DVD player for my 2 toddlers to watch movies in on the plane also.
