These tips are great!
My only tip is if you are staying at a Disney Resort take an afternoon to explore. The resorts have so much to offer. Walk around the resort see all the themeing, WL is incredible. Take a bike ride , or rent the water mousre boats. Go for a swim. WL lodge has activites all day, rubber duck races, magic cookie hour and tours.
Also go and explore other resorts. We found the petting area aFW this way and the Horse Barn. Walt Disney World is much more than the parks and there are a lot of things to do for free.
