OK....... Reality check!!! ;-D
Vacation Travel can be stressful. If it isn't the kids raising a ruckus, it's horn-honkers... and if your flying, it's that kid in aisle 21 that won't be quiet and let you relax.
This problem can be easily solved with a Noise Diffusing Device... most commonly known as Ear Plugs. They can be purchased at Walmart and most drug or sporting goods stores for about $1.
I converted this simple pair of foam Ear Plugs into a simple necklace with a few color-coordinated rolled Paper beads and thin strips of metallic tape rolled into beads.
I found the fascinating Paper Bead Instructable right here: https://www.instructables.com/id/How-to-Make-Paper-Beads/
You really don't need much besides your imagination when deciding how to glam up your Ear Plug Necklace. Just purchase the style of Ear Plugs you prefer, keep your beading materials light... and choose a pair of ear plugs that'll match your outfit. ;-D
Remember: A well-rested Mom is a happy Mom... and if Mama ain't happy, ain't nobody happy! Sorry Dad... you're on your own! ;-D
