My Usual method for Attacking any Amusement Park is Getting there at opening and hitting the LOW Capacity attractions first. So at MK. I go to Tales with Belle, then Peter Pan, Winnie the Pooh, Tea Cups, Barnstormer, Dumbo, Little Mermaid, It's a Small World, then Mikey's Philharmagic. (I come back for the Carousel at night). Once 7 Drarfs opens I will probaly hit that right after Tales with Belle.
Then I hit Haunted Mansion. Normally this is where I would get a FP for Splash Mountan and then ride Big Thunder Mountain, Eat Lunch at Pecos and then go relax on Tom Sawyer Island. Then was usually time for the FP at Splash. (Now I guess I would have to try to schedule the FP for around Noon for Splash)
Then it was getting a FP for Jungle Cuise. Followed by Pirates, Tiki Room, and Aladdin. By then it was time for the FP on Jungle. Then I would catch Hall of Presidents and then move onto Tomorowland. (one land left and it is usually only 3:30/4 PM at that point)
I would get a FP for Space, then enjoy the People Mover, Stitch, Laugh Floor, Buzz Lightyear, Carousel of Progress... then it normally would be time for the FP on Space. Then it was Dinner at a restaurant or Cosmic Rays, Get a Spot for the Night Parade, Fireworks, then finish the night with repeat rides on Big Thunder, and end with the Carousel, or do the Astro Orbiter if I really wanted.
The 3 FP+ picks for me would be Splash, Jungle Cruise, and Space Mountain. Those are the only ones I ever used FP for.
I've used that system for the past 12 years. Never had wait over 30 minutes for anything. (Most were 20 or less) Not sure how im gonna have to change things with the New System.
