Well , in HKT , Mai Khao isn ' t really a preferred area .. Beach gradient there is rather steep , etc .
There are quieter , non touristy parts .

Forgot to mention that SS Yai Noi now has indoor showers .
If you decide to go there , request for those with it .
Can combine with Puri or Trisara .

As for Amano'i , you have to be there to appreciate the spectacular scenery & beauty of being in a national park . Privacy .
Photos can ' t / don 't show & don ' t do justice to the ' atmosphere ' experienced when present .
Those who have stayed at an Aman will understand the difference
It is a one of the sprawling Amans , not like Puri pavilions .

If you do go , best combine with Metropole in Hanoi or PH in Saigon / HCMC - for flight connections / jet lag buffer .
Taking into account too that this is a honeymoon

We are just back from Pulo . We really love the idyllic ' peace ' of this tiny private island with the best soft sand which is cool at all times .
We did hang out in our casita a whole lot as it was ' unusually ' hot . Should be nice in Mar .

Be sure to read kurl ' s TR .
Pulo has done improvements since then & is even better when one already thought things were just about perfect !
" .. the Pool Club serves Asian and Western food, the Beach Club serves Spanish food, the Lagoon Club has Vietnamese for dinner only, and the Picnic Grove pizzas at lunch. "
The Lagoon Club is now Thai with a Thai chef & not Vietnamese which you can still request . Food is really good .
Stargazing is nightly & the runway has been & is being upgraded - not dirt
If you do choose an Aman property , remember any request isn ' t too outlandish , and they won ' t bat an eyelid when you ask either .
We & others will likely be able to give you further updates once you have decided on your destination ( s ) .
