[Noah930]

Have spent a lot of time in Yarmouth, and can't think of a beach that fits the description (of the large staircase). I'll double check with my in-laws, who live there. There are homes on the bluffs that overlook Cape Cod Bay often with stairs that lead down to the beach, but the cliffs aren't what I'd call huge. The beaches with the bigger cliffs seem to be on the Atlantic side of the Cape, off the top of my head.

Any more information? On what road is the timeshare? Any other landmarks on the beach?

edit: Mrs. Noah grew up in the area. She can't think of any beaches in West Yarmouth that fit the description. She suggested the Outer Cape, or along Cape Cod National Seashore.
