Hector Suites is a quality facility run by locals. Though it does not have the same feel as the marriott down the road, the rooms are nice, the facility is across from the beach, and the price is about 1/4 (25%). If you want a large pool area, all the bells and whistles, and a private beach, then pay for the marriott. If you want to travel around the island rather than sit at the hotel while saving a bundle, Hector is the place! You will also probably mix more with the locals.
One piece of advice for anywhere you stay: if walking home late, take a cab, only because the dogs claim their territory when the people all go to sleep. Curacao is working on this!
