Thank you for your insights.

I have decided to just insist on Window-type ACs. I reckon that it being situated in an island, maintenance of splits would cost a lot for a house that we just live in 5-10 days in a month. As a consumer, I predictably would have to shoulder the travel and lodging expense of the serviceman, aside from his PF. It also occurred to me that I don't want to waste the little time we spend there repairing or having the splits serviced. With Window-types, I can just pull it out, diagnose it and bring it to the mainland if I can't fix it. Buy a spare and use it.

After this renovation, we're going to do another project. That's where I think it's more viable to use splits. I probably would stick to single-split though. I realized that if the condenser of the three splits conks out, there'd be three rooms without an AC. That can be a disaster for some. In a beach island, it can get really humid at times.

*Badsekktor: I think Kolin sucks. Haven't encountered a good unit yet and an owner who swears by its durability.

Now, if you're the installer, you'd like an unreliable brand like Kolin because that'll mean repeat jobs for you.
