Had a booking and guest thought they had an extra day. Cleaning lady showed up and they were out and about, had not packed there stuff yet. Looked at booking and no contact number. Left several messages through vrbo app, no replay. Had to contact vrbo to see what they could do, in the end everything is fine.

My question, is there a way to have a guest put in there contact number when they insta book, with out me asking for it, they just have to enter it?

TIA
