OK, let's clear up the confusion. There are TWO big outlet malls on International Drive, one at each end.
The big outlet mall near Disney World in Lake Buena Vista is the Premium Outlet mall. The even bigger outlet mall on the far end of International Drive near Universal Studios is the Prime Outlet mall.
They share some stores- both have Nike, Adidas and Reebok, Nautica, Ralph Lauren and Tommy Hilfiger- but they also have some big differences. More on the differences in another post, but if you are looking for Saks Off 5th and Neiman Marcus, you need to go to the Prime outlets.
Near the Prime Outlet Mall, you will also find some great peripheral shopping. In Festival Bay Mall about a 1/4 mile down the road, you'll find a BASS Sports superstore, Ron Jon's Surf Shop, Sheplers Western Wear and a Van's Skate Park and shop. There's a very good pizza spot right in the center of Festival Bay, great for tired children and their parents.
