To only a few hours in Epcot would have just frustrated our grandchildren, and us, too. Yet, I have known people who have done it, and when I asked how they liked our particular favourites, their responses were along the line of “What? I didn’t know that was there!”
While it is certainly possible to cover the required ground to hit only the ride-type attractions, all the beautiful details will be a blur. Rather than giving yourself an unsatisfying experience, consider spending your time in another park, repeating some favourite attractions. Save Epcot until you can savour it!
Our grandsons loved this park from their first visit at 3 &4 yrs, when we wondered of we would ever get out of the Living Seas Pavillion! Now, they are teenagers who keenly appreciate the festival foods, but still want to see every attraction and show.
