As a seasoned business traveler, lemme tell ya, once you walk away from the counter getting billing errors fixed is very, very difficult. But if the person at the counter is not fixing the problem right away, your first call (before you talk to the first of many members of management) is to your credit card company and tell them you are disputing the charges, you WILL follow this up with a letter. Do this while standing at the counter. Take copious notes, document the name(s) of every one you deal with, and note the gist of the conversation. Escalate quickly and efficiently, the opening salvo with what ever manager you deal with first is, "who is your supervisor and how do I reach them, I know that you are going to resolve the issue and I want to be able to tell them how you handled this problem so well"
If satisfaction is not quick, write letters, write lots and lots of letters. For a situation like this send everything certified receipt return so that you know they got it and who signed for it (for a $500 loss, the investment in $10 of receipt return mail is minor). Write every level in the offending organization and every level in lateral organizations(these organizations have staff meetings and let’s face it everyone likes to gossip, you increase your odds of being heard if a the offending organization’s rival has a good story to tell at cocktail parties)... and provide a cc list at the end of your letter. In this case, the hotel manager(s) of all the values, VP of resort operations, customer service, and operations for WDW and DL. BBB, FTC, the FL state agency that oversees rides and attractions which I believe is part of agriculture. Throw in the FL attorney general. Tell them the story, as you would tell it here, or to a friend. Include as much detail as possible, and outline what steps were taken to resolve the problem so far, and how this is not yet satisfactory. Include all your contact information, and give a date that you expect to hear from them on this matter before you will escalate the situation further. A deadline, and further embarrassment can be a powerful motivator.
The one thing I will caution you on, it harping on the security tape. The folks you talked to probably don't have access to that level of security, as those cameras are usually more to prevent employee theft then robbery, etc. Once the letters and complaints get to the right level, either they will review the cameras or use other means to determine what really happened. And be consistent, and persistent but above all else polite.
Oh and part of the home work is already done...

a letter to everyone on that list is a good start.
