A balanced first-timer plan focused on Sanya, with one island day and optional shopping — without overpacking the schedule.
Check in near your chosen bay. Keep day one light: beach, sunset, seafood. Day two for full beach or water activities.
Pick Wuzhizhou or West Island. Start early, return by late afternoon, keep dinner easy.
Choose either a scenic/cultural half-day or Haitang Bay duty-free, depending on your trip goals.
Morning free time, then transfer to airport with pickup buffers if you shopped duty-free.
Possible but tight. Better to keep 5 days Sanya-focused unless flights force a Haikou overnight.
