We got the official guide, there are lots of character meals that were great, in mgm there is a buffet with the little einstiens, in epcot one with the princess, etc. Also, we went on the website ahead of time and figured out what we could all do together for each park and which rides we would have to split up (due to height requirements). The other great thing was the book told about the rides, the the bugs life thing can be really scary for kids, my 4yr old LOVED it but he's fearless and sleeps totally in the dark, no hall lights, no nightlight, so when it went pitch black he wasn't scared. Also a stroller is a MUST...if you don't have a double, Disney will rent them at the front of each park, but get there early (you maybe able to reserve ahead of time). Even for a 4 yr old that never uses a stroller, you have no idea how much that walking is for them, it's a lot for you and remember each step for you is like 4-6 for them! Plus we left the park at the peak time each day, right after lunch for naps and then went back, it was well worth it!! If you can get to the animal kingdom early on certain days they have the characters out front before they open. Have a great time! Oh, the toy story rides are also games, so if they're great because with the older kids you can really play and the younger kids just like seeing their favorite characters (there are 2 toy story rides, one in magic kingdom and one in mgm). The princess thing looked great, we didn't do it because I have a son, but I swear every girl there had it done. Also, little girls wear those princess costumes like clothes at every park, if you have any, bring your own, they cost a fortune there. We took my niece and wished we had brought our own to save the money on the same thing. Also, if you do the princess meal at the castle (which I highly recommend) make sure they're dressed in the princess costumes if they're into that. When we went 4yrs ago with my niece, she was the ONLY one there not in a costume for the meal and now every where you go the girls are dressed up. Also, to see the princesses at the magic kingdom, you have to go to the character tent in the little kid land in the back directly behind the castle. They have the evil step-sisters on the right side of the castles, but only at certain times. Make sure to get time kids for as many of the parks as soon as you get there, so you can play the best day to go to whatever one based on the nights shows, etc. The mgm has the best night show!! Also be prepared...all the great rides end into a merchandise shop for that ride that you have to walk all the way through to leave. Have a great time and if you have any other questions let me know (we went this past march with my son who turned 4 in may).
