We try to do Busch for two days everytime before heading to Orlando.
We get there at opening and go straight North through Morocco and up to Nairobi and get right on the train. The ride around the animals early on has a lot of activity that doesn't seem to be there later when it's hotter. We get off at the Congo Train Station, hit Congo River Rapids first. That far part of the park is pretty empty then and we work our way down through the Jungala, (The Jungle Flyers are a cool ride for kids 6-12 that gets HORRIBLY long lines later) and Stanleyville ,( Flume, Tidal Wave, Tiger Habitat...),areas that are also empty then and enjoy the rides with very little wait.
From here you can go to Timbuktu where there are kiddie rides and a carnival like atmosphere,IMO, with games and such. OR South into Sesame Street Safari of Fun. Both good things for smaller kids AND by the time you get down here the BIG SURGE is up where you started when you got off the train in the Congo.
*Special Note from my DH. The turkey leg vendor across from the Orangutan Habitat, in the Jungala Area, has HANDS DOWN the best smoked turkey legs as DH compares to Disneys and Universals. In his words, " They sure know how to use that small smoker!
Egypt has some cool and fast roller coasters, the Skyride, ( which is very cool to see the animals from above ).
Hope this helps a little. We often have to split out plans between our older adrenalin junkie daughters and our 4,9 and 12 year old neice and nephews.
