We love going in Oct.! You will have a great trip! However, I would say skip Ak and go for Epcot. Just in my opinion though...we dont' care much for AK and love Epcot. The food and wine festival is neat, I think, because there are so many little carts with specialties from other countries. I loved seeing all the different foods. However....since your question was what else would we be missing....Figment, The Land, The new ride Soarin', Test Track, Spaceship Earth, The World Showcase with all it's culture and excellent restaurants and shops, Maelstrom, El Rio Del Tiempo, Illuminations....lots in my opinion! Epcot and MK make the trip to WDW for DH and I. It's a really awesome park, and I would hate for you to miss it!
