We stayed midweek in November. A great time to visit Santa Cruz (the Boardwalk will be closed midweek). Walking distance to lots of local restaurants. Excellent walking path/bike trail along the coast of Santa Cruz that was north of the Sea and Sand Inn.
Rooms were surprisingly quiet although the back was on West Cliff drive.
Free continental breakfast, free wine and cheese in the evening (good wine I may add). Nice places to sit at tables on the bluff of the beach. A good "base" for visits to Monterey too (about 40 minutes away). Much less expensive than staying in Monterey may add (almost half of the average price).
Room was spacious (we got the lowest price room). Bathrooms are really large in size (enough for a wheelchair if you need it). Wireless WiFi in all areas.
I highly recommend the Sea and Sand Inn and we will be back.
