Spent 2 nights here last weekend with my family. The room that we got which was a Terrace Twin was quite small and there was no view of the sea but we could not complain since breakfast and dinner were provided for 2 pax and children below 5 years old get to eat for free.
For lunch, you can head over to Sematan town which is just nearby or take a 30-min drive to the nearest town Lundu.
In terms of activities, we tried to book for the boat trip as recommended in the resort's website but weather conditions did not allow that to happen.
In the future, I would recommend to go for the 6-pax chalet as those are the only ones with direct view of the sea and don't stay for more than a night.More
