Sauron: Frodo, get up. It's a glorious new day!

I always used to be upset about inadequate hotel curtains until I started taking a sleep mask on every trip. Absolute game changer. And ear plugs, of course.

That's why i always travel with electrical tape, it solves tons of problems. With curtain cracks i just overlap the curtains an inch and then tape them together that way.

Can you still hear your alarm with earplugs? Was thinking about trying them

Yes. Never had a problem where I missed it.

The clothes hangers with the pants clips - tack those curtains together and don’t forget the do not disturb sign!

Yes. They only reduce the volume, they don't eliminate sound entirely. Alarms are still fully audible and effective at waking you up.

I find it hard to believe electrical tape will stick to curtains. Really?

Yes really. Remember it just needs to be holding it to the side by a single inch, so there's almost no tension pulling it back the other way. Also you might be imagining the tape vertically, but it's actually a couple of stretches of tape going horizontal across both curtains

I cannot ignore the feeling of something in my ears. Very disturbing.

Depends on the kind of earplugs

I always liked this trick

I can usually get them to close tight by tugging enough on the entirety of each curtain so that they 'want' to bunch together in the middle. I hope that makes sense. This trick may not work with all of them.

The trick others have posted with the hangers that have clips is very clever, I'll definitely keep that in mind. Some hotels have hangers that you can't take off of the clothing rod, however,

This sounds like a job for Captain Binderclips! A couple of medium sized packed in your bag doesn't take up too much room.

Don't you just keep overlapping from one side or the other unill they don't come apart? Like overlap the curves from one side to another, sometimes takes a few tries. Though I guess air flow may impact it but the curtains are heavy and air flow is usually gentle. That's how I deal with all curtains when I want it dark. Not just a straight close.

Not helpful for sleeping but i like noise cancellation headphones for planes
