Hi Jennifer!
Well, after you tell your 8 year old son to stop looking at your 5 year old son with his "mean face" and tell your 5 year old son to stop telling your two year old that he can "only go on the baby rides," you should be ready for some fun at Hollywood Studios! Just kidding, having three boys is awesome and I can't imagine my life without them!
Depending on the height (and courage!) of your 5 and 8 year olds, they should both be able to ride Tower of Terror. Yes, it is dark and scary, but my 9 year old loves it. I think that my 5 year old went on it just to be able to brag about it - his face in the picture is priceless! As far as Rock-n-Roller coaster is concerned, your 8 year old will probably think that it "ROCKS," but it will probably way too intense for your 5 year old. Of course, the littlest bro can't ride either of these.
Now for attractions that the whole family can enjoy! In addition to the ones that you listed, we all love Muppet-Vision 3D, even though my kids really don't know who Kermit and Miss Piggy are. How sad is that? Anyway, we also love the High School Musical 3 show and the brand new
Toy Story Mania! attraction. My boys usually want to skip Voyage of the LIttle Mermaid because of the girl cooties!
One of our favorite counter service restaurants is also located here. Toy Story's Pizza Planet is a great diversion from the heat and the pizza is really good! If you have time, the Great Movie Ride has some really cool parts - Indiana Jones, cowboys, aliens, etc. All in all, we love to visit Hollywood Studios and one day is plenty to see everything once. Oh and don't forget that Fantasmic is a great way to end the night.
I would love to hear from you again!
Much pixie dust,
Jackie S.
