Skinny dipping in a hotel pool after hours in Omaha.

I was simply curious if anyone knows of a hotel in the Omaha area that you may be able to skinny dip after hours and the staff turn a blind eye. I'm certainly not looking for a wild loud time. Just a relaxing swim for a bit. I realize it's probably going to be an older hotel, but choosing the right one with an indifferent staff is a little challenging.

Does this have to be a hotel? I know a few private pools where this would be welcomed.

No, not necessarily. That was the only avenue I was aware of simply because I don't know anyone that has a private pool.
