I stayed at the Pangulasian (was there about 4 months ago). What resort are you considering?
No, you can't expect the same level of service as an Aman (the rates reflect that) but I really enjoyed my stay there. The room was $700 but came with a private pool, now all my wife wants is private pool when we travel LOL.
The diving / snorkeling was okay, so don't make a trip just to enjoy the diving .
The grounds are all nice and well manicured. The food was good, though this isn't a michelin restaurant. Also, don't expect to be catered too. There are no GEM or Butler really so you need to schedule activites on your own.
If you want something more affordable then Aman, this is the place. If you can deal with not being catered too, this is a good choice. If you wnt ultimate luxury and be catered too at every turn, this isn't the place.
