Yes. You may use last years cup.
Last year and this year is ok Next year it will be different
It's a little different this year. I'm not sure for how much longer, but as of yesterday they were still filling last years cup for 99 cent fountain drinks, $1.99 slushies, & they are giving free cups of water. I go to spots where you can fill your own, so I can put little ice. Also take a bottle of water in, then refill it (for free) at the self serve stations.
They are using last year's cups again this year. So you can still use them.
You would have to buy a new one, but the are offering free ice water this year.
I think you could still use last year's cup at your refills this year are dollar 99 not 99 Cents if you get a new cup your refills will be $0.99
They have cups for each season, so you'd have to get a new one!
