I do not know how else you would handle all the customers flowing through, you certainly are not going to sell MobileTrust or GID at check-in. Its on the bill and if you want to use the unsecured WiFi have at it, the risk of being hacked now belongs to the customer and not the hotel. I would imagine they will suppl;y a disclaimer if you opt out. I do not think anybody will have a problem with being charged for a secure WiFi at a few bucks a day with all the hacking that is going on. I am sure more information will come out soon...
