I stayed at the end of October and was given the option to decline Mousekeeping. For a $70 gift card, it was a no brainer for the two of us. They sent it via email and I was able to attach it to my iphone Passbook. Theoretically, I could've used the Passbook barcode on the phone at the parks (at least according to the CM at the Front Desk). Though, in the end, we just had them credit it to our room charges. I recall them saying they could post the gift card if you wanted but it was much easier to have it emailed and on my phone. I didn't even need to bring it out when we got it credited to our room as it was already attached, waiting for our permission.
