Hi Holly,
Here’s a track plan for my 3’ X 9’ layout. I prioritize running trains over structures. You may want to consider using a single figure eight track arrangement. It provides some variety over a simple loop. I used the AnyRail track planning software trial download. It’s limited to 50 pieces but that should be sufficient for your needs.
Is it a coincidence that someone named Holly has a gorgeous Christmas Village? I don’t think so!
John
