Even if the housekeeping crew made your room impeccably tidy and sanitized after the last guest, the staff still might have forgotten to do one important thing that’s actually critical for a good night’s sleep: turn off the alarm after the previous guest’s use. And if that alarm has been set for some unpleasant hour—maybe for a previous guest’s early-morning flight—you’ll want to make sure you turn it off before it wakes you up at that time, too, says Brandon Berkson, hotel expert and founder of the new HAP Concierge trip planning service.
