Traveling for the holiday season? We thought so. Guess who else will be, too?! Annoying armrest hoggers, loud cell phone talkers, and that guy who only eats tuna on international flights. Since we can’t control the actions of others -- especially that screaming baby that seems to follow you your entire trip -- we’ve partnered with Marriott Hotels to make your travel experience a little more tolerable. We got seven travel experts to spill their favorite hacks and must-have gadgets on-the-go to make your next trip an easier one. Harness Solar Power!
