Renting a pool villa is an excellent option. They are a good value, you get your own private pool, many bedrooms and bathrooms, your own laundry, and many other amenities. We like to get a house when we travel with all th ekids. It just makes more sense for us.
I didn’t have much luck the last time I searched for one in the Universal area however. You may have better luck with the houses near WDW.
