Just the tips:
1. If you look at Disney as a list of rides and experiences and you have to check off each one, on some schedule designed to maximize the number of rides and experiences you have, you sound like a boring person and you're doing it wrong. Look at it this way - Disney wants to entertain you, wants you to think their place is special - not just another amusement park, and Disney is really good at it. Walk around with no-where to go, and just watch your kids. Some of my best experiences are interacting with random characters in the streets (the suffragettes on Main Street, or Cinderella's evil sisters). Talk to them "where are you headed today? Is there any news we need to know today?" They're well trained. They have some random street dance party about once every two hours and my kids got to dance with Aladdin and Judy Hops from Zootopia - they thought it was cool and still talk about it. Disney parks are not just sidewalks that lead to a series of rides, they're more than that and there is something cool around just about every corner, if you have the right mindset. Even the places and people outside the park gates, the ferry rides, the monorail, the workers/cast members. Each is unique and special - try to figure out why/how. It's fun.
2. The Halloween party is the best ticket of the year. Yes, some of the rides are closed and the entire Magic Kingdom isn't open, but you're not some glutton from the long line at wal-mart. You've got a brain and you know you're at the best, family-friendly halloween party in the World. You will see a headless horseman riding a real horse, the cast members come out of their shells a little and act loose, you can get your face painted. They have different characters out at this event that are less common on regular days (more villains, less of the happy peeps). One of my favorite moments was boarding the jungle cruise at the MNSSH in costumes. My family was all peter pan costumes. The guy said "ok, we have tinkerbell, Wendy, Captain Hook and (looking at me with my costume) you must be Captain Ron." It was funny. Again, if you're on the "I want to ride the most rides per minute of anyone in history" agenda, save it - go to Six Flags in Dallas or some carnival in the Burlington Coat Factory parking lot. If you're thinking "how do I have fun at a Halloween Party with my kids?" you'll love it. Go to the Haunted Mansion after dark. They go a little farther for Halloween.
3. Take it easy. Unless you typically walk or are on your feet 12 hours per day, don't try to do it on your vacation. Start early in the morning, take some stuff in. When it gets hot and you lack motivation, go to your hotel, cool off for a few hours and nap, and then charge it again at 3-5 hours before closing. This way you'll have 8-10 quality hours per day. If you don't take a break/nap, you'll basically be a zombie by 1pm, and waste the entire evening. Also, spend one day on your vacation at a hotel pool chilling and having drinks. I cannot stress strongly enough that the breaks, days at the pool and naps will increase your energy level and happiness immensely.
I spend 7 days per year there and I keep going back every year, because when I travel there with my kids they provide the entertainment and I get to play along with my kids, and don't have to provide the show.
