This is exactly what the email says after you rent from
dvc rental store:
"If asked during check-in, please refer to yourselves as a guest of **** ***, not a renter. Please note, Disney will have no record of any transaction regarding the
DVC Rental Store. All of Disney's dealings have been done through ****.
Please be aware, check-in will be no different than any other regular resort stay. The reservation is in your name, so you will need to provide your name, a photo ID and a credit card to the Cast Member checking you in. Rarely, if ever, will the member's name come up."
I booked before all this hubbub lol. I think by telling you not to refer to yourself as a renter and that you should say you're a guest, is solidifying that being a renter could spell trouble with DVC, just my opinion or else why tell us that.
