From Windsor Hills, it will take you no more than an hour. We stayed at WH last Thanksgiving. There's also a better way to get to I-4 that will put you a little further West when accessing the Interstate.
When you exit Windsor Hills, you make a right on to 192 from Old Lake Wilson Road. Stay on 192 until the second traffic light, which is Griffin Road. Make a right. This road will lead you on to I-4 westbound also but you'll pick it up two or three miles further west (and most importantly, away from the 192/I-4construction zone.) It definitely saves a few minutes.
Have fun!
