The Property Owner never provided the check-in instructions. Two calls to VRBO support resulted in their inability to get in touch with the property owner as well, and no reservation for which to check into.
The reservation was paid in full at the time the reservation was made, one month before.
My payment is being refunded, thankfully.
Scrambling to book last minute same day hotel reservations after spending 2.5 hours on the phone with VRBO Support and still no reservation was the cherry on top of a disappointing start to our weekend.
Thankfully for us, we booked other accommodations to compensate.
