5.) Guest shows up. Hotel checks in guest anyway.
6.) 3rd party ignores hotel.
7.) Hotel freaks out.

...and I say that because I've sent the form only when unable to send photo ID and credit card image and then subsequently forgotten to send the promised addon. Some hotels are mega strict about this. Another scenario would be the hotel didn't (as so many do) notice the 3rd party checked the "Room and all incidentals" box and felt the guest wasn't authorized to charge anything to the room without a separate form of payment for incidentals. I don't know why so many hotels overlook a box on their own form.
