The small parking area is adjacent to the hotel -- off of the side street, not the main street. It is barely wide enough for three cars and they pack the cars in 2-3 rows. So, upon arrival -- for us, mid-afternoon -- there is ample space to park and unload. By the next morning, the area looked like a small parking lot. We had to leave the car keys with the front desk so they could move the car as needed. We did not use the car while we were in town so there was no issue here; and the car was easily accessible on the day of our departure. But, what a pain for management!
