Hi, Connie! You can pay your gratuities with cash, not a problem! You can also pay for any extras with cash (such as appetizers, alcoholic beverages, etc.) If you change your mind, you can use your credit card or charge to your Key to the World card if you added charging privileges at check-in.
In Downtown Disney, my favorite quick service location is Wolfgang Puck Express. They have delicious pasta entrees, pizza, and my favorites: BBQ Chicken Salad or the BBQ Chicken Quesadillas. I think it is the best quick service location around!
