This can be very confusing. We had PS in Aug for 2 adults and 1 child, I called a few days before to change it to 1 adult and 1 child. I was already charged on my credit card for the 2 adults and 1 child but was told it would cost close to $25 anyway.
I used my DDE (Disney Dining Experience) card when I got my check which should have been $25.42 less 20%. Somehow, instead of getting discounted 20% I was charged extra, it was so confusing that I didn't even know where to start by trying to figure out what was wrong with the numbers.
Somehow I paid an extra $12.12 on top of the already charged $25--which would cover tax and tip but when I take the 20% off of the $25 and add the tip and tax it sure doesn't come out to $37. It's about a $10 discrepancy. I didn't know who to follow up with it, I wasn't going to make a special trip back to MK's CRT to try & solve the problem just to have them confuse me more. And, unless I got a really good CM at CRO I'd end up spending an hr on the phone with them (which would end up costing more than the over charge).
It probably wouldn't have happened if they didn't charge the deposit...I know they've had the need to institute this policy but I just can't shake that I keep feeling like I've been ripped off.
