My husband and I stayed at Delfins for 2 weeks in a garden view studio. The resort is brand new; opened in November 2017 and is quite beautiful with a great location on the water. In hindsight we should have booked a 1 bedroom with ocean view for the few extra dollars. Although the studio is quite adequate for a short stay I found the very narrow kitchen sink with no counter space to be a little frustrating after 3-4 days.
The staff were all very welcoming and helpful. The restaurant on si[... lire plus]te is excellent but very pricey if you intend to eat there everyday. The bar menu is more reasonable and has quite a few very good sections.
The one issue we had with the bar restaurant at Delfins is the fact that their menu was only available in Dutch. It does not change every day so I don't understand why it is not translated to English. All other documentation has the English translation. Also one of the bar staff was unable to explain the menu to us and did not even offer to call over another employee who was more fluent in English. We were left to gamble with our meal orders. Luckily this was the one exception to otherwise excellent service.
Although the resort advertises a full PADI dive operation on site it does not yet have dive boats or a dock. They have a dive store, a tank refilling station etc. But divers must drive to Port Bonaire (a few minutes down the road) to meet up with their sister dive operation. Delfins advised us that the docks are going in at the end of March and then they should be able to provide full dive services shortly thereafter.
I would go back to this resort once their dive operation is fully operation.
