I think that there is 2 diferent duck tours, if I remember, the green camo ones drive thru the woods and onto the lake... The red white and blue ducks do more of a in town sight seein tour....
Noah's Ark is a GOOD time, although if you go on a weekend, be prepared to spend half your time waitin in line... Family Land is a lil smaller water park, but its cheaper and they let you bring in a cooler of food, saves a few more bucks...
