@soocoolsim, I think that's a great idea for you to provide the landscaping, etc to the base lot and have 2 different color schemes/designs for us to choose from to keep the consistency.
@ciane, you are right about possible routing problems with only a 1 tile walkway, so I think I'm liking the 5 wide best and having the sleeping compartments 3 deep with a 2 deep aisle. I was initially thinking the 4 deep so that I could add on an all-in-one bathroom next to the 3-tile bed, haha, but I guess we can make different configurations for the compartments (like single rooms with no private bath and having more deluxe accommodations with a bathroom). I like the double staircases and double doors as well! :)
I am really bummed that you aren't going to include ITF, as I think those big round windows would like best on the train, hahah, TOTALLY KIDDING!! lol
Speaking of windows, just curious if were going to use the windows from Roaring Heights that you used in your Elf express trains, or something different? I was looking at our window selection and so many are either too tall, too short, or don't sit low enough or have too many glass panes, etc. I was liking that rectangular one called India Inspired Bedroom - Timeless Views window, as it looks most like a picture window.
I'm excited to work on one!
