A portable DVD player is  something you would like on a long trip,

anytime I have spare time I just take out my portable DVD player and watch my favorite moves anywhere I may be,

where ever I go and what ever I may be doing I can always pull out my DVD player out and watch any DVD move I have such as stark track, superman, and moves for my children,

on long trips children tend to get restless  and unruly, then is when having a DVD player comes in handy
