I have stayed at the HGI Bang Tao 3 times now (December 2021, March 2022, April 2022) all one nighters due to "quarantine" requirements. Although I only completed the first stay overnight as my negative Covid tests on 2 occasions allowed me to leave before bed time & my house is only about 10 minutes away! I too booked lowest cost rooms & was upgraded to King Premium Balcony rooms twice - the other time not. I echo the above comments in general, although I found breakfast a real weak spot, poor quality all around IME - I did feed this back so hopefully its better now. Recommended for a low cost non-resort style stay.
