We haven't expected the boat to be so crowded, it seems like they cooporate with other tour conductors to collect customer from several companies/ platforms to join 1 trip. The waves were strong the day we come, so both of us and other guests had terrible motion sickness.

For those who have motion sickness, please be noticed that you will have to survive 1 day on the boat (from 8AM ~ 3PM), quite a bad experience for me.

The diving spot was not as beautiful as the one I experienced several years ago at Blue Cave, not worth 1 day on boat, I've expected a lot more. 

The staffs were not nice as well, we have 2 girls, both vomitted due to terrible motion sickness, no one did care and ask uf if we are ok. Worst service in JP I've tried.
