My favorite outlets in the area are very easy to find. They are right off I-4, near I-Drive South. If youare staying in the Vistana (not the V VIllage) they are VERY close to that area. You can also get there pretty easily from 192, but that's not the ideal way to exit WDW to get there. A better bet would be to exit WDW near the DTD resorts and Crossroads Plaza.
Those Outlets have a Disney Character Outlet which is a great place to find Disney stuff onthe cheap. Much of it is actual park stuff from the last season. Great place to get souvies for those back home.
They also have a Nike outlet (I think that's what it was) for sneakers, and a good place to get beauty products (like OPI nail polish, salon-brand shampoos)- in case you forgot either.
For little girls, there's a Heartstrings outlet that has beautiful sweaters.
