Neck Pillows: Baggage or Brilliant?

My kids were gifted some kid-sized neck pillows full of pleasing beans and sand.  I was worried about one more thing to drag around.  Nope!  These are super because they make reading a lot more comfy and they give an air of luxury to an otherwise dull plane flight.  Would I take them on a 3 month trek across Asia?  Nope.  Will I bring them on the next cross-country trip to see relatives?  Absolutely!  They get plenty of use between flights on the bed at home too.
