One of my criteria for motels is that the courtyard be sealed. With a heavy bike, maneuvering in a confined space on gravel is a challenge. Of course, covered parking is a real bonus when there's rain or morning dew. Late check-ins are very helpful doing our style of travel.
But I digress- I know what you are looking for and hope we can build a useful list.
