I've got to ask.. when your daughter was crying and screaming that she didn't want to go back to the daycare, did you ask her why she didn't want to go? And why did you make her go if she was having that bad a reaction? Isn't that the first warning sign that a kid has been abused/molested...?

In any case, that's terrible. Rather than asking for them to refund your trip (because that's just going to make it sound like you want money; as a general rule, the best way to get a refund is to never say the word "refund" at all. People are a lot more willing to help someone who isn't obviously after a few bucks) you should find out who you need to contact about the day care center on that particular cruise ship, and alert them to the problem. If you have to, call the health department, I'm sure they'd be thrilled to know that Disney allows its guests to wallow in filth.

I don't care how difficult a day care job is. Having feces splattered all over a playground and then continuing to let children play on it is unacceptable.
