A little-used feature at hotels are the free late checkouts. Just because your official checkout time is 10 or 11 am, doesn't mean you have to hurry on those lazy layover days. Simply call the hotel office and ask if you can have a free late checkout. Then you can leave the hotel and have a great breakfast, see the sights...and THEN come back and pack up. Common late checkouts are until noon or 1 pm. I call that a SWEET freebie!
