Hi Jenny,
Unfortunately your question has been cut off but I think that I am right in saying that you will have one day at Walt Disney World left after spending one day at Epcot, Disney's Hollywood Studios and Disney's Hollywood Studios as well as one and a half days at the Magic Kingdom.
If you still have a theme park ticket left for your last day, I would suggest that once you have visited each of the four theme parks you decide between yourselves which was your favourite park and spend your last day there. (Or, you could spend the morning at one theme park and the afternoon at another if you have added the park hopper option to your park tickets)
If you don't have a theme park ticket left for your last day, I would recommend visiting the
Downtown Disney Area where you could do some shopping, enjoy a meal or even venture 400 feet into the air in a giant tethered balloon at Characters in Flight.
I hope that this has answered your question, but if not, please feel free to visit us here at the Moms Panel again.
Wishing you a magical trip!
