lol, hotels are not that tech savvy. 99.9% odds if you're faxing a hotel domestically it goes to an actual fax machine. Every property I've ever worked at, seen or have knowledge of is still using some large old school fax/copier straight out of 2000 which is still used frequently for all of the numerous CC auth forms that are still used. You would be shocked at the number of travel agencies that want forms faxed to them and want to return them via fax.
