We have a PS for 8:30 for the princess breakfast at Epcot. How long will it take to walk to the restaurant? We will have DD4 and DS2 in a stroller and will be driving our car from Pop. Also, when we are done eating, can we walk around the world showcase? It looks like it doesn't open until 10 or 11. Do they let you walk around just the shops are not open or will we have to leave the area? Thanks for any advice...
