I made this drink last Thursday from the Unofficial Disney Parks Drink Recipe book. The strawberry flavor was definitely there and there were strawberry seeds in it, but I think they're supposed to be there. I haven't been to a Disney theme park for that drink, so I wouldn't really know. Anyway, I think it would've tasted sweeter if there was any unwanted help who added more water to make it "healthy" as in less sugary.
UPDATE: I tried the real version this time as it is in the drinks book and it was a bit sweeter than the watered version.
