Hainan couple trip
Couples do better with one hotel and an empty morning than with a checklist of bays. Pick the beach first, then add a single contrast day.
The beach base
Yalong Bay if you want a long beach and fewer street vendors. Dadonghai if you want restaurants outside the hotel gate.
Book a room that faces the sea only if the price still feels fair after you compare a garden view. The sand is the same.
One extra scene
A dawn or late-afternoon hour at Riyue Bay changes the picture without a second week. Go back to the same hotel that night.
Skip the group evening show unless you already like that kind of night. A walk on the bay is enough.
