yes
Yes you can
Yes you can use it at adventure island, aquatica and sea world as well, if is not the first day all your refills would be $1.99
You can refill for 1.99 each time but you cannot 'recharge' your cup; that's where you pay about 7 dollars and have unlimited refills during the day. You can recharge your cups at the other 2 parks; not sure why.
Yes and at SeaWorld too
