I only bring for breakfast as I would miss out on the yummy foods for lunch/dinner.
We bring 2 boxes of cereal & one has to be one that I will eat so it is usually Rice Krispies or Cherrios (they like them too).
I bring pop tarts. I have brought bagels & butter-my son is allergic to dairy and they don't have Earth Balance in the World just the Fleishmans & that has no taste. I didn't bring milk this time & bought it there. But I may next time-the soy & regular milk that don't need to be refrigerated.
I have brought oatmeal packets but that was pre kids & I really have no interest in getting up & walking to Captain Cooks to heat it up only to walk back to the room to eat it.
For snacks I have brought down potato chips, tortilla chips & salsa, pop corn, RK treats (non-milk ones thanks to Target brand!), non-dairy/peanut/treenut cookies for my son, gum (but that only comes on on the plane), some candy-again for the plane.
I think I brought banana's but only because they would of gone bad if I left them at home.
Pepperoni slices in a bag (they don't need to be refrigerated until they are opened) as my kids like them & Ritz crackers. I brought a can or two of tuna since my 6 year old (the one with the allergies) likes tuna.
I think I have done single serving packets of some snacks as well since they are easy to throw in my bag & this way the kids don't fight over "he got more then me."
