I don't know much about hotels in ac as I don't venture there much unless i need to...or pass through on way to the boat ramp.
But if you go make sure you take your kids to the Aquarium in Gardners Basin...then go get yourself a mason jar drink from the ale house
. My girlfriend works at the Aquarium...that is probably one of the few kid friendly places in AC. Rain forest cafe is also a cool place to take kids. Food isn't anything special but there's a bunch of cool fish.
