Not
DVC, but a cash resort room experience: My sister and I checked in. I put my cc on my MB at the front desk during check-in. Day one, it worked correctly, I was charged using my MB, and I never bothered to check it after that. Mistake. Because from day two onward, the charges from my MB all went to my sister's cc, not mine.
This was in 2019, so perhaps they have a better handle on this now, but since then I just use my cc instead of my MB.
