ok ok let me think...
fast pass...use it!
buzz lightyear ride...do it ( i even say drag your child kicking and scraming if you have to, they will love it)
fun foods....whispering canyon for breakfast at WL (they have a fun boat ride over to the magic kingdom), hoop dee doo revue (book now), liberty tree tavern for dinner in MK, chef mickeys for breakfast (a lil over rated but still fun), 50's cafe at mgm, pizza planet for counter service at mgm, rose and crown at epcot (make the ps for 7:30, it has to be 7:30, then request an outside table for illuminations), cape may at BC, coral reef at epcot (arrive early and ask to wait for a tank side table, its all about the tank side table).
do epcot backwards. ahev a "late" breakfast at the boardwalk, then walk over to the world showcase at 11 when they open. walk around the world. then do the front of epcot mid afternoon, when the crowns are making their way to the WS. you will have the place to yourselves. dont forget the kid stops in each country. also get each child a passport ot be stampes in each country, my son loved this.
dont take your kids on alien encounter even if they are tall enough. they are way to young for the max scare of the ride.
