What's better than spending the longest day of the year looking out at the city of Chicago?

This sounds like the coolest sleepover in history.

The longest day of the year is June 21, and you can spend it at the 360 Observation Deck at the John Hancock Building this year.

So here's the deal.

If you go to this sleepover, you'll spend 12 hours on the 94th floor of the John Hancock Building, which is where the observation deck is.

You probably won't be doing too much sleeping though, because this is a huge party, including some super Chicago-style dinner, snacks, beer and games.

I'm talking Lou Malnati's, Revolution Brewing beer and Garrett's Popcorn.

That's what you get for the basic (slightly hefty) price of $94.

You can pay a little more and get a little more too, like a full-year pass to the observation deck for you and a friend, or a helicopter tour of Chicago.

On top of all of that, it's a charity event benefiting M3: My Block, My Hood, My City, so you can write off that sleepover price tag.
