You can get all day soda refills added to any existing cup for like 6 bucks by the way.Be aware that it is only available in certain restaurants in the park. But yeah, considering an all day soda bottle costs the same price(although you dont have to get ADD) it seems to be pretty popular.
Not sure what the DWI liability is in Florida but in VA it's one party responsible ir at least was a handful of years go when I was ABC licensed. Basically as long as you are of legal age it's YOUR responsibility not to drink and drive and it nearly impossible to sue for it if someone you served drives and wrecks. Which is not to say there are not rules about limiting drinks and over serving but that gets into more complex areas. Honestly I be less apposed to the idea if the price tag was a little steeper to make it less inviting to young people but I can very easily see where this might make Sea World the go to park for young college aged kids for all the wrong reasons and hurt the parks family friendly reputation.My initial thought was about the liability, because people have to drive home. But then I remembered that until recently, Discovery Cove was all you can drink. So, I guess SEAS has that problem figured out somehow.
