## Things to watch

### An on-site PC is required for two-factor authentication

Ddnayodotcom puts the integration through two-factor authentication, so the property needs a PC on site. Without one, the Ddnayodotcom integration is hard to use.

<Warning>
  With no on-site PC, two-factor authentication cannot be completed and the Ddnayodotcom integration cannot proceed.
</Warning>

### Multi-night bookings arrive split into single nights

Book several nights on Ddnayodotcom and VCMS receives that booking **split night by night** into several bookings. A 3-night booking becomes 3 bookings, a 15-night booking becomes 15.

<Info>
  Ddnayodotcom sometimes bundles separate bookings into one. That can make the night count come out wrong, so VCMS splits Ddnayodotcom bookings into single nights. This way, inventory stays accurate even when part of a booking changes or is cancelled.
