We've all been there. A day at a theme park or beach can really wear you and your family out. You decide to crash at the nearest motel and chill out for the evening with a movie: a very expensive movie offered through the automated system in your room. With the portability of DVD players or laptops and services like Netflix, Hulu and even YouTube, there's no need to fork over an extra $10 here and an extra $6 there. You can pack some of your kids' favorite DVDs before you leave home, get a rental online or drop by the neighborhood Redbox. Plus, if you pack a couple laptops, your children can watch the latest wacky animated comedy while you fade off to sleep. At least you can rest easy knowing there'll be money in your checking account when you wake up in the morning.
