Even with the cargo bay/shuttle complex taking up such a large space, I still have a few gems in the secondary hull I can't wait to get to. Other than engineering up at the top of the hull (yes, I will be giving my previous version from 2015 a facelift), there's also the botanical garden. MSGTTE also has a botany lab directly aft of the garden, and then the ship's swimming pool placed at the aft end of that deck, which I think would be fun to imagine. The guide also has some engineering support facilities like the primary maintenance complex (which would be fun to prop out) complete with large industrial fabricators, and a turbolift maintenance facility somewhere in there as well. And let's not forget that the cargo bay complex itself has it's own transporter facility that I've been itching to model for years, as well as various lounges that are between the cargo bay's upper level and the hull, plus the lifeboat section flanking each side of the cargo bay's mid-level. There's a ton of fun stuff in the engineering hull...much of which we've never seen! God. I'm salivating. Like I said, still totally invested in this project. I just have to recharge my batteries for a bit!
