See if you can find where the aliens are hidden (denverpost.com).

I haven't been to DIA in a decade so I'm sure the places to eat and drink are all different. I don't envy you a 10 hour layover anywhere.

Been there lots. It's a good airport.

Go find the creepy mural and take a picture

Player piano and killer horsie statue.

If I'm thinking of the right airport, there are lots of those people movers everywhere. You can hop on one and basically explore all the arms of the terminal super fast to check the shops out while getting some exercise periodically.

Here's what I do during a layover.

1) Walk around the airport until I find a place that isnt too busy and has somewhere for you to sit on.

2) Look on the floor for power points, most of the time they are well hidden, or you need to lift a floor flap or something to access them. But they're there.

3) Plug in laptop/phone, earphones/earplugs, and play video games or do work: time flies.

You can also just buy some food and do the same thing in a restaurant, but most of the time the good spots are taken.

I'm sure there are other options for those more well off, but I just don't have that mindset. Maybe check in to the airport hotel and have a nap+shower?

Flying sucks.
