For larger homes, I personally have found Emerald Island to be a better bet. EI has a ton of homes that large, plus on their floor plans, you can get 4 bedrooms which are ensuite. What I found in Windsor Hills was mostly homes with two ensuite bedrooms. That might be just my preference. Prices are comparable, or even lower at Emerald Island vs. Windsor Hills too. You can check out available EI properties at stayatemeraldisland.com. Enter your dates, and the desired no. of bedrooms, and it will pop up a list for you.
Good luck! I found some pretty good rates for our Feb trip at all the resorts.
