Hi, Rachel! Thanks so much for popping in with your question. I have recently chatted with several Guests about their room window decoration plans. I love that so many windows are being "dressed up," as it shares the magic with so may other Guests. My daughters love to walk around our Resort and see what amazing windows we can find. If you need some ideas on how to make your window extra festive this holiday visit, check out Pinterest for some very merry ideas.
As I mentioned before, I have recently been on window measurement missions for other Guests. One such Guest was staying at another Walt Disney World Value Resort, which will have the same window measurements as your Resort.
Looking at that answer, it looks like you will need around 16 feet of lights to go around the perimeter of the window.
If you plan to decorate the window sill, I did also call about its measurement one day and found it to be 5" to 6" deep.
I hope this information helps you plan your jolly holiday decorations, Rachel. Please let me know if you have any additional questions!
