Yes we like the Tiki Room, but we definitely do not have to do it every trip! Can't skip the Teacups as that is DD3 favorite, and one of mine too! That music just gets me in a happy mood everytime I hear it. Tom Sawyers we skip only because there is no way I can fit through the tunnels holding DS, and IMHO, DD's are too little to go themselves because sometimes you don't know where they will come out! But your DD is a perfect age.
I think you will have plenty of time to do almost everything atleast once if you stay till closing Friday, open to close Saturday, and get there early Sunday! When we do trips like that, we get on pretyy much everything once and our favorites a few times! Good luck!
