Spa Hotels in Mersing

First i want to review on booking experience. I was so pissed off with Trip.com booking. I entered 3 adults upon search & result showed an option of 3 occupancy room with full-board package for 2 adult. There is option for full-board 3 adults however since the first option was cheaper i was thinking to arrange my own for the additional 1 adult boat transfer & not require the meal package. It was shocking that when i reached the check in office it is mandatory to pay for the 3rd adult boat n meal package to the resort. My question here WHY trip.com put the option for 2 adult knowing the resort does not allow the 3rd person to check in??? This is a scammm for me because i entered 3 adults requirement at the first place for the booking. Both resort & trip.com are not synchronise with the information. Now going to resort stay experience: The resort staff were all great & the service was also on point. However, the condition of the resort was so below my expectation. I paid RM 700+ per night & i don’t feel worth it. Everything was super outdated & worn off. Especially the bathroom. The floors were cracked open & was swarming with bugs & insects & some people might get allergic to them. The bedroom is self was okay & comfy. Also food-wise, they served a lot of seafood & didn’t ask if anyone was allergic or not which one of us is. For RM 700 per night i expected it is included some activities we could do at the resort however it was disappointing that everything was chargeable whereas they are non-motorised & doesn’t even use resource / maintenance such as kayak & snorkel gear. The only nice thing at the resort was staff friendliness & the food taste.
