Here are some ideas:
* When my kids were younger, little Disney themed gifts would appear when we left the room or overnight...from Tink or Mickey as a special surprise. They always felt so special
that Mickey left them a gift!
* check out the Creative DISign board as mentioned -- you will be inspired to make custom t's, autograph books, invitiations for character meals, etc. I made my auto graph books by printing clip-art pics of characters we were likely to see on cardstock and having it bound at Kinkos. The characters loved the custom books and gave a lot of attention to the kids.
* read a guidebook and be familiar w/the rides and shows -- they are well done, but if kiddos aren't ready, they will hate them. The shows are LOUD and can be scary (some rides as well), anticipate if fireworks will be too loud or late, etc. and plan accordingly! Some rides LOOK scary but are fine, so you having background knowledge will really help. I believe most rides are available for "previews" on Youtube.
* character meals are the most efficient way to interact/collect autographs - otherwise have a plan when you will meet characters, as it can take a huge chunk of time.
* Light up toys and glow bracelets etc are great fun at night, and you can save a bit of $$$ by bringing ahead of time....or if Tink/Mickey delivers as a surprise.
* don't forget to plan pool time -- most kids love the pools as much as the parks
* We still love to do the Kidcot fun stops around world showcase in Epcot - kids color a mask then collect a charm from each country....you can also make/purchase a passport and get it stamped in each country. This really enhances the experience. It can also be fun to try a piece of candy/snack at each country over the course of your trip. Another thing we do in Epcot is try on (and I take pics) of the kids wearing the various hats from each country - great photo ops w/viking hat and sword and Troll in Norway!
* since you are traveling in July, consider a misting fan!
* the
Lego Store in Downtown Disney is fantastic and has outdoor building stations that are wonderful for kids of all ages!
* we are trying the Pirate League pirate makeover on our next trip. There are also fun things like face-painting, Barbershop confetti 'do (in the MK), etc., if you think he would enjoy it.
* Somehow Disney snacks are extra special!!! We love frozen lemonade and really any kind of ice cream from a snack car!! Also, popcorn (in themed bucket), pretzels anything from a candy store is great!
* If you have a chance, pop out to the Boardwalk an evening you are at Epcot - there are excellent street performers, snacks and even midway games.
* my kids love to try a few of the midway games at Animal Kingdom.
* check out the exceptional playgrounds at AK and DHS - they are fantasticaly themed and great for kids to stretch their legs! There is also a Pooh playground at MK. They all have squirty water features tho!!
Welcome to the Dis and happy planning!
