As the mainstay motel of Aptos at Rio Del Mar beach, it would benefit the Rio Sands to take stock of their furnishings periodically (replace worn, creaky pull-outs), refinish rusted scuffs in bathrooms, and check whether ceiling fans are truly doing their job. The perennial continental breakfast has dwindled to toast, oatmeal, waffles, and cereal--no fruit, yogurt, or bagels any more.
