Yes, the do have a refillable cup at Knott's We got it in February-and good news for me, they had just switched from Pepsi to Coke! Yeah! Your refills are free the day you buy-they put a colored wrist band around the bottle to designate the day. You don't have to show a receipt.
It's $12.99 for one (with a large soda at $3.79 you'll save money if you get 4 drinks.) Plus you can use on future trips and it's only .99 for a refill.
Coke Selections.
We don't normally get sodas at KBF since they were Pepsi. We wanted a snack and went into Coasters for fries and saw that they now carried Coke. According to the employee they had just switched over. We'll be going this Thursday for the opening of their Boardwalk area. I will be bringing my cup with us.
You can even get Knott's Boysenberry Punch!
BTW, you must have their fried chicken! If you don't go to Mrs. Knott's you can get it to-go right next door (that's what we do). If you do ask for them to get if fresh from the kitchen. I was told this tip years ago by an employee-this way the chicken is hot! (and so good!)
Don't know about US but I assume they do as well. We got one last year at IOA in Orlando and the employee there told us he thought we could use it at US Hollywood too! Their deal was different. Refills are .89 (inc. the day of purchase) There is (was a discount) if you bought more than 1. I wish I had seen it before I bought ours and I would have asked someone in line if they wanted to buy ours together.
Soda cup was $7.99, refills .89. We also bought the popcorn bucket for $4.99 and refills were are also .89. I don't think it saved us money on our visit but my DM and DSis used our containers last month and saved money that way.
You'll notice that KBF is more for drinks than US. Also than DLR. This has been the case for years. Another reason why we usually haven't bought drinks at KBF before the refillable cup.
