Any recommendations?

Look for the next iteration of House of Servitude. I posted a review of one from Last spring.

Not sure what in particular meets your criteria, but We have a perfect interrogation room set up at Atlanta Dungeon. Very easily can keep someone down there for extended periods of time, and have a large collective of Dommes that could be your prison wardens. I've held many kidnapping/captive prisoner sessions there.

Hello and Thank You SO much for your rapid reply. Especially at holiday time I am ready for it to end.

"criteria" wise, You definitely just checked a ton of the boxes. I apologize to be so brief in this response now, but will review your website and follow any application and booking instructions there.
Sorry...out of town pesky holiday visitors are cramping my style

Are you looking for an actual prison type environment with real cells etc?

The only one I know of in the US is the Edge Jail and Dungeon. Located 1 hr 40 minutes south of San Francisco, it combines a large, well equipped BDSM playspace with a wing of real prison cells including a padded cell and a harsh solitary confinement cell. They are rental only and you have (had?) to make your own arrangements for a Domme to accompany you. Unfortunately their website shows them as "currently closed"......

Although, a recently published bondageliberation video with Elise Graves looks like it might have been shot there so perhaps they are still renting to established Dommes and customers?

I've always thought spending 24 or more hours there under the control of a Domme would be an amazing experience. I'm not really into the whole institutional prison play thing but the fact it has a playroom with an extensive collection of gear combined with secure cells of varying degrees for harshness seems the best of both worlds.

I logged in to repeat what Mistress Ultra Violet was saying about Atlanta Dungeon. I have had the joy of keeping a handful of prisoners there overnight, some more than once, and quite convincingly. There are a number of possibilities for confinement as well as options for multiple Domme wardens/captors.

Thanks Jess.
Yes , in fact I have decided on that facility and was thrilled that Ultra Violet reached out.
Having trouble with links on her site to get the ball rolling with scheduling, etc....sure it was a temporary glitch and will reach out this weekend if thats the proper procedure.
Thanks!
