I think your family will have a ball. There are great coasters at IOA that will likely thrill the kids (Hulk, Dueling Dragons) There is also the the Spiderman ride which has great effects and is not to be missed. My DS 12 loves Dr. Doom's Fear Fall. I have yet to get on it! There are some great water rides at IOA as well. Poseidan's Fury is worth doing at least once. Check out the show schedule. Once when we were there they had a BMX style stunt show. Since you will be there during the holiday season be sure to drag them for a visit with the Grinch! You will probably enjoy the photo for years to come.
Over at US the kids are sure to love both Men in Black and the Mummy. Make a point of going to the Horror Make Up Show. They will also probably like Back to the Future and Terminator--though those are not favorites of ours. Your 10 year old will probably get a kick out of Shrek and maybe Jimmy Neutron--if he is a fan of the Nick cartoons.
A big hit with my son is NBA City on City Walk. I hear Nascar is also popular with the youngsters--though we have not been in there.
Have fun!
I think those are the highlights for teens and preteens--but if you have time, all of the rides are worth hitting at least once.
