I noticed that carnival has drinks of the day. For 6.95 you can buy their drink and refill it for 4.95. Can you use the same glass for refills all week or do you have to buy the drink each day for 6.95?
Yes, you can keep using the glasses all week for refills. You hand the waiter your glass and ask for a refill and they give you a new one. Just make sure to take it with you when you leave the pool area each day so that you can bring it back the next day for refills! Enjoy.
