I've extended stays without needing new keys. There could be wireless updates, or resetting the lock is done when housekeeping preps the room.

There are definitely multiple solutions that don't depend on a server to authenticate every unlock.

I'd imagine the locks in most hotels don't require an internet connection. Frankly I'd be horrified if my hotel room's locks depended on this horrendous WiFi.
