Err, err, the one at ABC.
I went for 2D1N package last year with some of our fellow divers here as well.
I would say I wouldn't be going back to ABC anytime soon.
Some of us stayed in the dorm room, which they say was very hot and stuffy. Some of us paid slightly more to stay in a twin sharing fan room in the nearby accommodation, oh boy that was some climb up to the room every single time. It's really basic as well, but most accommodation on Tioman island are like that, especially the smaller beaches like these.
As for the dives itself, it was alright, we only did 3 dives with them. We had the whole boat to ourselves since we had quite a group. They weren't the most enthusiast DMs I've had but they were ok, satisfactory.
My never-to-return reason is mainly because of what happened after the trip. I left my wetsuit to dry at the DC and completely forgotten about it (my bad). So I contacted their ABC office over the phone and emailed them later as well to check. I offered to reimburse the cost to get it shipped back to me or brought back but they said that one of their owners is going to KL that weekend and I can collect it from him when he's in KL. Great, that was awesome, so I contacted the number that they gave me. No answer most of the time, text message reply was really slow. Manage to set a time and date to meet up right smack in the middle of KL but kena stood up in the end, waste of time. Finally replied hours later and then tried to compromise with his timing and location again. I did manage to get back my wetsuit after days of frustration and no apologies whatsoever. Yes, it was my mistake for leaving my stuff behind but I trust this could have been handled way way better with more responsibility from their side.
So if you ask me, there are many other dive centers on Tioman island. Their prices may be one of the best, cheapest and all, but I'd rather pay more for better services and experience elsewhere.
I sangat menderita stay in that dorm room. hahahahahah cannot sleep at all because panassss
