Go to Sanya for six days, stay in MGM Yalong Bay for two days, and rest in Tanglaya Show Hotel in Sanya Bay for the next three days, but I don't know how to arrange the scenic spots and time.

It's not convenient for you to stay in Yalong Bay for five nights. Living in Yalong Bay is only suitable for leisure and vacation. It's a little inconvenient to go to the scenic spot. I suggest you rent a car and drive by yourself, or find a local travel agency to let the master take you to play.

Six days and five nights, with four days of play time, I'll make a good trip for you for your reference:

Day 1: Large and Small Caves

The next day: Yanoda

Day 3: Wuzhizhou

Day 4: Nantian Hot Spring

If you still want to go to the scenic spots, you can go to Wuzhizhou in the morning and Nantian Hot Springs in the afternoon, so you can save the next day and go to other places to play!

It is inconvenient for you to travel in Yayalong Bay. If you haven't booked your accommodation yet, I suggest you consider changing it: Dadonghai+Yalong Bay or Sanya Bay+Yalong Bay.

Dadonghai and Sanya Bay are relatively close to the urban area and their respective scenic spots, so it is convenient to travel. There are buses in Dadonghai and Sanya Bay, where you can go to any scenic spot or take a one-day tour. It is convenient to take a car to the scenic spot for free. These are not available in Yalong Bay!
