Take the kids! They will totally love it... My older kids talk about it all of the time...
I also wanted to add that you can bring kids on the Pirates ride at a very young age. My littlest was on my lap looking around wide eyed at 11 months. She was more scared when she was 2.5 (but not very scared). If your kids are scared you may be able to tweak their fear with lots of positive stories in preparation.
THE BLUE BAYOU RULES!!!
