Nothing to do with what else you can do but you can get some money towards the shopping.
When you go to Discovery Cove for your dolphin swim make sure you take your Flex ticket with you and when you check in tell the reception you don't need the 7 day sea world ticket and you will get a credit back for each of the tickets. It was $30 but may be more now as that was last year. It's not generally advertised but all the guests we know who have asked have received the refund.
So you have another $90 to spend, if you ever get time to hit the shops.
