Yesterday I had a friend in town, and the two nights prior we definitely took advantge of Chicago's nightlife and all it has to offer.

In other words, we were severely hungover and were going through bottled water like Lindsay Lohan goes through AMG Benzes...

We didn't want to go to a bar (obviously), and we had just eaten at Reza's, but were looking for something LOW key to do. For example, if I were in Newport Beach, Duffy Boating would have been the perfect activity. Museums and "learning" were not of interest given our state; and the beach was packed.

It would have been nice to chill at a good resort, do any of the better ones offer daily access to their rooftop pools?

We'd thought about paddle boats by LP, but that was a little cheesy, especially since we're two dudes and that's more of a couples' thing to do lol.

Any suggestions for this purpose?

Sightseeing cruise off Navy Pier.

East Bank Club has a rooftop pool, though I'm not sure if you can get a guest pass without knowing a member.

If you want to chill outside and the obvious beaches are full, head to Lincoln Park--lots of green spaces are uncrowded. I often see people chilling out on the grass north of Diversey Harbor, and I'll head to green areas around Belmont Harbor.

Drinking isn't a requirement at places like ESPN Zone and Dave & Busters, but they can still be fun to hang out at.

Go to the movies?

I was thinking of the architechture cruise ^

The Pen does with a spa treatment or I would assume for a fee as well.

If you can deal with crowds of small children, I've always found the zoo/aquarium to be amusing, even (especially?) in that slow-moving, post-hangover torpor. I sometimes prefer to sweat it off, though, with a bike ride or canoe trip on the river.

The Zoo actually is a good idea...free and just a place to walk around.
