Portable Blackout Curtains This is another travel must-have if you are traveling with littles (or honestly, even if you don’t have littles but you like your rooms to be super dark!). These portable blackout curtains have both suction cups and velcro so you can stick them to any window and the velcro allows you to size the curtains however you need them. I have two of them now and they are perfect for helping the kids to sleep in a darker room and not wake up crazy early when we are on vacation. LTKKids LTKHome LTKTravel
