Since I have to pass the front desk to go upstairs anyways, and to get the breakfast voucher at properties without lounges, it seems kind of pointless. The main use for a mobile key would be entry to my room if I forgot (not misplaced/lost) my key(s) in my room and left without them, but had my phone on them. As I said in my last post, I've never had the mobile key work at any property, and I've tried on more than one phone.
