I think now that I was a little overzealous when I decided that. The bigger the ship, the more room to spare and the more comfortably everything fits, but I think everything can just about be squished into a 725m frame. Plus, the atrium behind the bridge is such a perfect fit for the domes at the top and bottom of the saucer and to fit behind the bridge in front that it can't possibly be by accident. That said, I'd love to see the CG models of the shuttlebay and engine room superimposed over the Enterprise. Are any bored ILM employees reading this?
