Yes there are on a few, but the only one strictly enforced is the new highly advertised (hydro-magnetic) Aqua Rocket (which BTW totally sucks). Aqua Rocket seats 4, but your party has to get on a scale and must weigh less than 700lbs total or some members will have to ride separately. Thunder Rapids has a maximum of 900lbs, but not sure what the maximum number of people are in a single raft I believe 4-6 depending on size. Dark Hole has a scale in the middle of the line but nobody makes you use it, and I don't know the limit - it's a 2-person ride, signs state they have single person tubes but they didn't on 6/15/18. I don't know about Dragon's Den it was closed.
Yes the rides have weight limits most are 350 I believe. If you go to thier website and look at all thier rides it says on each what it is. I'm a fat chick, and I still enjoy raging waters alot. I dont have balls to do most rides, but thunder Rapids is fun. River and wave pool also always work perfect for cooling off.
Somewhat, at several of the rides they'll have to any your other rides weigh in.
I don't think so you can call to be sure.
Only some rides
I am not sure, but I know for the newer ride the aqua one they do go by weight limit.
