I remember correctly, that was one of the many places at the water parks that require cash only. There were several that did not accept credit cards, room IDs or the dining plan.
I wonder why that is? Maybe the Disney execs don't consider the water parks part of the "World", or maybe it's just a way to get us to spend more $$, knowing that we're trapped in there with no other choices. Hummm. Something to think about.
I did (thanks for the reminder), and I was asking just in case they hadn't been added yet. But it seems that hardly anything is there, outside of Typhoon Tilly's and Leaning Palms.
