Here is my beef. First, I would think they could go directly to the water parks during park opening hours. Not so much during the middle of the day.
Second, when you are going to the water parks, you are usually, hauling a little bit a stuff. When you are going to DS, you are, typically, not. To have to get off the bus and haul all your crap to the literal farthest bus stop from where they are dropping you at DS is so annoying. I suppose I would be less annoyed if it was the bus stop next to where they dropped you off.
Third, I am not paying to go to DS, I am paying to go to the water parks. I think you can just take me there.
Honestly, I don't complain too much about things at the World , but this is one of those things that really, really bugs me.
