Since when does a day only consist of 18 hours? On a recent trip to Arizona, I stayed at a very comfortable Sheraton Hotel property in Scottsdale. But to my dismay, check in time was 4:00 PM and checkout time was 10:00 AM. Now I know that the hotel needs time to clean the rooms and thus the check in/out gap, but it appears to be widening. I remember checkout was typically noon and check in was 1 or 2. The hotel needs a few hours, but a 6 hour window? Seems like they need more staff to provide better service to the guests!
