Not to Oasis resort but been to Bohol...its a great place to tack on the end of a trip to say Cebu or even coming back from Palawan, but once you've done the river cruise and seen the choc hills not much else...
We consider staying there for a 1 week diving holiday during Chinese New Year. I know for sure that the dive shop at the Oasis is very good. Would like to get a bit of a review about the resort.
