Do they have fast past

They do not have fast pass. If you have someone in your party that has a disability but is able to enjoy the rides they can stop at the front desk to get a wrist band that will allow you and 3 others to jump to the head of the line but you must go to the exit of each ride and somehow get the attendants attention

I assume you mean fast pass similar to Disney parks, they don't. There is no way to skip line at any canobie attraction

Yes. It's all pretty much fast food.
