Can I use my refillable souvenir cups I bought at Busch Gardens to Adventure Island and get 99 cent refills?

Yes you absolutely can.

Yes

Yes you can

Only on the same day of purchase

Try googling it or calling them. I'm not exactly sure. Would be nice if you could.

Yes you can. Water and ice is free and fountain drinks are like $0.98 ea

I don't believe so.

I think so

No has to say Busch 6

I believe so
