Oh, I did that as well! You can see more on my island... board thingy, with the link under my username (still new here, getting used to the terms and stuff

)
To the right of my plaza is the shopping area, and just north of that is my museum. To the left is the main "neighborhood", and a small section of beach that I turned into a beach neighborhood with a fun, public beach (outdoor tables and benches, vending machines, towels, a bonfire, etc.)
Get further from resident services and the dock and, in general, my towns get more rural and rustic and undeveloped. I designed everything with the plaza as a hub, as I intended when I first saw the map I selected (like I said, I was super excited to get RS so close!)
Honestly, at this point, I have no clue how I'd work an island WITHOUT RS right there
EDIT: Also, SmrtLilCookie, I love the edging on your brick paths! Are those custom designs, I'm guessing?
