Yes, we will be doing that this year and we've done it in the past.
We have old plastic window candles that will be in every window. We also will put lights along the deck railing, a wreath on the door and a tree inside. We'll go through our decorations to see if there's other stuff we can do outside. We don't have blow-ups or anything like that.
We have a spiral tree that folds flat so it's easy to bring. It has lights and garland built in and we'll bring some cheap plastic decorations to make it look more like a Christmas tree.
Feel free to decorate as much as you want. The outdoor outlets are in the middle of the cabin, between the two doors so you'd also need to bring outdoor extension cords.
