Updated PoLA Plan

In between golf, chores, and binge watching Game of Thrones, I did an update to the Revised PoLA plan based on some feedback from the client. He plans to reuse an existing staging level with a helix. Since he already had those built, it wasn't a big deal to modify the plan to include them. He also asked to include the option to include some ship models on the layout. Finally, he asked for suggestions on what to include in the second room, which the first design listed as future expansion. This version reflects those changes as well.
