There can be some debate about how high CO2 not to mention other GHGs got at the time. Nonetheless, there was no hot house. I don't even know what that term means. I suppose to some adherents that means going into something like the Carboniferous. That would be pretty tough given how much the mixture of major gases has changed, and the fact that the Equatorial Current can't circle the globe now due to the wall of The Americas and the near wall of SE Asia, India and Africa. The next opportunity for that sort of regime is hundreds of millions of years in the future.
During the last interglacial, all the coal, petroleum and natural gas was tucked away underground. Now it's not.
