We stayed at AOA in October.. Fantastic! We go to WDW and Universal every year and we always take the back road between the two. I will do my best in describing it, but I just know the way and not 100% sure what the roads are. When you leave AOA head towards downtown Disney and follow that road out of WDW. It ends at a stop light in Lake Buena Vista which I believe is 536. Turn left. Then turn right onto Palm Parkway. Follow this road all the way to the back entrance to Universal Studios. It turns into Turkey Lake Road and you will see a sign that directs you to Universal Studios. I would tell the cab driver you do NOT want to take I-4 but you want to go the Palm Parkway/Turkey Lake road back way. He should know what you are talking about.. Oh! And you will LOVE the Wizzarding World!
