Yep, they got them!
They offered to sell me one at Bleachers (pool snack bar) for $11.99. Since we were only there for a day we did not buy them, but the size of the regular soft drinks was soooo small for 2.19 that it would be worth it even if you were there for 2 days! They had the soda fountain out so you could get drinks even if the pool bar was closed. It had about 6 drinks (Coke, Cherry Coke, Diet Coke, Hi-C). It looked like they also had lemonade and iced tea available in seperate dispeners on the counter. I don't know about using them at shutters.
We had a great day at Vero and are thinking about taking the family there in Feb.
