Thinking about this I can remember a Marriott before mobile check in give me keys with my name only at check in using the elite line. Also a Residence Inn using mobile check in giving me keys with name only. A SpringHill Suites and Courtyard using mobile check in giving name and last 4 of credit card and given keys. A Four Points using mobile check in given keys with name only. In all cases they didn’t know me. Many times keys stop working between noon and 2 pm for 4 pm check out and keys refreshed with no ID just name, room number and expired keys. In any of these examples was proper procedure not followed??
