We got back last Saturday from Curacao. We initially booked Sunscape and spent less than 12 hours there. Once we arrived it was in such bad shape (I took pictures in order to dispute with my CC company if Hyatt denies my refund) that we decided to find another spot and went to the Marriott Beach resort. The food at Sunscape was awful. Not even up to 'meh' all inclusive standards. Just sad and below basic food.
We had an amazing time once at the Marriott. Staff were awesome, rooms were nice and clean, and the beach/pools/food were great.
#1 tip is to rent a car. Taxis are $15-30 one way. We rented a car and drove to Willemstad every day, found some awesome beaches and explored the island.
***best restaurant in Willemstad is Kome. Go on Wednesday evening for their tapas menu! And then go back for their regular menu another night. Ask for waitress Kelli and you'll have some of the best food and time of the trip!
Top beaches:
Grote Knip: chair rental is $5/chair and there is snorkel rental on site for $5.
Playa Marie beach is where the wild pigs are. Nice beach and cheap chair rental $3 with a ful service bar/restaurant on site
Playa Piscador: snorkel with the turtles. Rentals and chairs on site and don't pay for an excursion here. Fishermen feed the turtles from the dock all day so you're guaranteed to see them while swimming.
Seriously, DO NOT stay at Sunscape and check out the Marriott or Renaissance reports.
We already booked another trip for next year in October because of the amazing time we experienced. We can't wait t go back.
Edit: their busy season is November-April/May so I'd expect larger crowds. But I'd go in a heartbeat. We loved every minute of it once we made the resort switch.
