There is also a KB Toys in the Premier Outlet Center. It is off of 535 on Vineland Road. It is about 1-2 miles from DTD. You can see the outlets from I-4.
Premium Outlets is on the I-Drive trolley route. Don't know where you'll be staying but you could take a taxi to I-Drive (by the shortest/cheapest route) and take the trolley southbound. $1 day for adults, free for children.
