We saw it last year. Even as an adult, I LOVED it!! Dino-freak, DS (who was 3 at the time) was too young and pretty freaked out. I think the noise-level certainly contributed to his fear. So, I second the motion for ear plugs!!
Hmm..
I am concerned about the sound and the size, given that Mr W is 19 mos, but Mr W loves horses and cows and goes with us to watch football at a local eatery every Sunday and deals well with the crowds at the mall..
He loves dinosaurs and saw me looking at this trailer and cannot get enough of it either .. I played it pretty loud on the HD tv for him..
