I really really recommend you look into the Pirate Bayou cruise that leaves out of Port Orleans Riverside
It was outstanding for our 6 & 8 year old boys. Plus mom and dad get a 2 hour break !
They were fantastic with all the kids. Everybody got an eye patch, head bandana, temp tattoo, pirate bead necklaces, etc.
They fitted each kid for a life jacket at the meeting point and let the parents double check their work before letting the kids line up.
There were kids of all ages and they all seemed to be having a great time.
I've seen the one leaving out of the GF, and I would say the one from the POR seemed more ....adventurous...
The parents walked along the path to one of the foot bridges, and watched the pontoon sail away.
At the end, they march the kids into the lobby, to a treasure chest full of goodies and gold doubloons , singing and cheering pirate songs, it was very fun !
